Susie Matsuda and Patricia Matsuda - Relationship

Overview

The relationship between Susan “Susie” Marie Matsuda and her sister Patricia “Pattie” Alison Matsuda is defined by profound love layered over fundamental incomprehension, the bond between the quiet responsible daughter and the explosive problem child who represent different ways neurodivergence manifests under pressure. Susie, born August 1977, is five years older than Pattie, born November 1982. They are very different people: Susie is gentle, soft-spoken, careful, thoughtful, and the family caregiver who holds everyone together. Pattie is impulsive, physical, loud, fearless, and the family lightning rod who gets suspended repeatedly for defending Cody with her fists. Susie thinks before acting, processes internally, and hides her struggles effectively. Pattie acts before thinking, processes externally through movement and volume, and has highly visible ADHD-related support needs. Their relationship is characterized by Susie’s exasperated declarations of “Pattie, you can’t just PUNCH people!”; Pattie’s defensive responses that someone needed to be punched; and Susie’s fierce protection of Pattie despite her frustration. Pattie represents everything Susie isn’t—wild, brave, and uninhibited—and sometimes Susie wishes she could be more like her sister. Mostly, Susie worries constantly about Pattie getting hurt, both physically and emotionally, and tries desperately to protect her while knowing she cannot control Pattie’s impulsivity any more than Pattie can.

Origins

Pattie was born when Susie was five years old, the third child after Susie and two-year-old Cody. From earliest conscious memories, Susie had baby sister who was loud, physical, constantly in motion, completely fearless. Where Susie had been quiet baby who preferred gentle stimulation, Pattie was chaos from day one—needing intense physical input, climbing everything, breaking things, moving constantly. The differences were evident before either had language.

As Pattie grew into toddlerhood and early childhood, the contrast between sisters intensified. Susie was the “good child”—helpful, responsible, doing what was asked without complaint. Pattie was the “problem child”—impulsive, defiant, getting into everything, injuring herself regularly through fearless physical risk-taking. Teachers loved Susie and complained constantly about Pattie. Ellen fought for Pattie’s accommodations while also being exhausted by constant disciplinary meetings. Susie tried to help manage Pattie, becoming translator and mediator even in childhood.

The pattern of Susie as responsible older sister and Pattie as chaotic younger sister was established early and reinforced constantly. Susie helped with Pattie’s homework, tried to explain why Pattie kept getting in trouble, intervened before Pattie could do dangerous things. Pattie both appreciated and resented Susie’s caretaking—grateful for support but frustrated by being treated as problem requiring management.

Dynamics and Communication

The communication dynamic between Susie and Pattie is marked by Susie’s gentle exasperation and Pattie’s defensive bluntness. Susie speaks softly, carefully, trying to reason with Pattie about consequences and better choices. “Pattie, you can’t just punch people when you’re mad!” “I know you’re trying to protect him, but there are other ways.” Pattie’s volume control is broken, so even when she’s not angry, she’s LOUD. “Someone HAD to punch them!” “What OTHER ways?! They were hurting Cody!”

The dynamic includes Susie trying to translate Pattie to parents and teachers, explaining: “She’s not being deliberately defiant, she just doesn’t think before acting.” “She doesn’t mean to be disrespectful; she reacts before she considers how it sounds.” Susie’s caregiver personality extended to protecting Pattie from consequences when possible, running interference, and trying to help adults understand Pattie’s ADHD impulsivity rather than seeing willful misbehavior.

But underneath the caretaking was genuine sisterly affection and admiration. Susie said to Pattie: “I love you. Even when you drive me crazy.” Pattie knew Susie loved her unconditionally, never judged her the way adults did, saw her as whole person rather than collection of behavior problems. When Pattie got suspended for fighting kids who bullied Cody, Susie defended her to outsiders even while privately saying “but you really can’t keep punching people.”

Cultural Architecture

Susie and Pattie’s relationship exposes the gendered fault lines within the Matsuda family’s cultural architecture. They are two mixed-race, neurodivergent sisters whose different presentations produced radically different family roles and relationships to the systems that shaped their childhoods. Susie is autistic, while Pattie has ADHD.

Susie is the eldest daughter who masks her autistic struggles. Pattie is the middle daughter whose ADHD-related impulsivity, physical intensity, and emotional dysregulation are highly visible. The divergence is not simply neurological but cultural: eldest daughters in both white American and Japanese-American family traditions are expected to nurture, comply, and hold the emotional center. Susie’s pattern recognition, emotional attunement through observation, and preference for structured interactions channeled into this role so effectively that her neurodivergence became invisible. She was the good girl, the responsible one, and the child who did not cause problems. Pattie’s behavior violated expectations for daughters in both cultural traditions. She was treated as the problem child, the one who got suspended, and the one who required intervention.

The sisters’ relationship is shaped by Susie’s frustration with Pattie’s chaos and Pattie’s need for the validation Susie struggles to provide. Susie, who holds the family together through self-erasure, cannot understand why Pattie will not just try harder to control herself—a demand that echoes Pattie’s own demand to Cody and reveals the same cultural mythology, that effort equals capacity, operating at a different frequency. Pattie uses physical action when impulse, anger, loyalty, and circumstance collide; she sees Susie’s competence as evidence that being “good” is a choice Pattie is simply too broken to make.

During childhood, neither sister has language for the differences between Susie’s autism and Pattie’s ADHD or for the effects of birth order and gendered expectations. They struggle to see each other clearly because the cultural frameworks available to them—good daughter versus problem daughter, caretaker versus crisis—obscure the people underneath.

Shared History and Milestones

1982-1995 - Childhood:

Throughout childhood, Susie watched Pattie get in trouble constantly—climbing out school windows, jumping off roofs, punching bullies, and getting suspended repeatedly. Susie tried to help by tutoring Pattie in subjects she struggled with, particularly reading, which Pattie found agonizing; talking her through consequences; and mediating between Pattie and frustrated teachers. The caretaking was loving but also exhausting, adding to Susie’s already heavy load of helping with Cody and Joey.

Susie was also sometimes jealous of Pattie’s fearlessness. Pattie didn’t care what people thought, didn’t perform social niceties, said what she meant and did what she wanted. Susie, exhausted from constant masking and social performance, sometimes wished she could be that free, that uninhibited, that unconcerned with others’ opinions. But mostly she worried Pattie would hurt herself—physically through reckless climbing and jumping, emotionally through social consequences Pattie didn’t see coming.

April 1995 - Cody’s Suicide Attempt (Susie age 17, Pattie age 12):

When Cody attempted suicide, the family shattered in different ways. Seventeen-year-old Susie held seven-year-old Joey together, tried to support their parents, and processed her own trauma privately to avoid burdening anyone. Twelve-year-old Pattie punched a hole in the wall and then bolted upstairs, unable to face what she’d said or process what happened.

Susie understood intellectually that Pattie’s explosive reaction was one way she responded to overwhelming emotion. Pattie’s ADHD-related emotional dysregulation was a factor, alongside her age, terror, guilt, and the shock of Cody’s suicide attempt; none of those elements alone determined her response. Susie also felt exhausted managing everyone’s reactions while suppressing her own feelings. When Ellen went upstairs to comfort Pattie, Susie stayed downstairs holding Joey, being strong because someone had to be.

In the weeks after, Susie watched Pattie fight everyone—kids at school who said cruel things, adults who whispered, anyone who looked at their family wrong. Pattie’s violence was protective, defending Cody from a world that hurt him. Susie understood the motivation even while wishing Pattie would channel that protectiveness differently. They both loved Cody fiercely; they just expressed it in completely opposite ways.

Fall 1995 - Susie Leaving for Stanford:

When Susie left for Stanford that fall, Pattie lost the sister who’d helped translate the world, who’d run interference with teachers, who’d tutored her patiently when she couldn’t focus on reading. Pattie probably pretended she didn’t care—acting tough, like she didn’t need Susie—but then hugged her tight at departure. Susie worried about leaving Pattie to navigate school and family dynamics without her support, trusting parents to manage but knowing how overwhelmed Ellen already was with Cody’s recovery.

1995-1998 - Distance and Phone Calls:

During Susie’s first three years at Stanford, communication with Pattie was probably minimal. Pattie wasn’t a phone person, didn’t write letters. Ellen updated Susie on Pattie’s ongoing suspensions and disciplinary issues. Susie worried from distance, feeling guilty about not being home to help, trusting Ellen and Greg to manage but knowing it was hard.

Spring-Summer 1998 - Pattie’s Pregnancy (Susie age 20, Pattie age 15):

When Pattie became pregnant at fifteen in spring 1998, Susie came home for summer before her senior year. This became one of the most important periods in their sister relationship. Twenty-year-old Susie, home between Stanford junior and senior year, provided crucial support that was different from Ellen’s maternal care—not parental guidance but peer connection, someone close enough in age to relate yet experienced enough to offer wisdom.

Susie sat with Pattie during the worst of borderline hyperemesis gravidarum, held her hair back when she vomited, brought water and crackers, validated the experience without trying to fix it. She provided emotional support during the weeks when Pattie was off ADHD medications and completely unable to regulate or manage executive function. She gave Pattie space to complain about Ellen without the “I’m your mother” dynamic, offering sister support where Pattie could be honest about frustrations.

They had conversations about being a mother, about fear and capability, about whether Pattie could do this. Susie told her: “You’re already doing it. You go to appointments. You take care of yourself. That’s strength.” When Pattie expressed terror about not knowing how to be a mom, Susie reassured: “No one knows how to be a mom. You figure it out as you go.”

The summer deepened their bond in ways previous eighteen years hadn’t. Susie saw Pattie’s vulnerability, her terror beneath the tough exterior, her exhaustion from pregnancy and being off medications. Pattie saw Susie’s gentleness as strength rather than weakness, learned that quiet support mattered as much as Pattie’s loud defense.

August 28, 1998 - Susie’s Departure:

When Susie had to leave for Stanford senior year on August 28, 1998, at 8:47 AM, Pattie was 29 weeks pregnant and desperately needed her. Pattie clung to her sister, sobbing: “I can’t do this without you.” “I don’t know how to be a mom.” The separation was agonizing for both. Susie reassured Pattie of her strength, promised to call frequently, reminded her that Ellen and Evan and the family would support her. But leaving felt like abandonment.

For Pattie, Susie’s departure was loss of peer support at exactly the time she needed it most. Ellen’s maternal care was crucial but different—having sister close to her age who understood and validated without the parent-child dynamic mattered enormously. Susie leaving meant Pattie wouldn’t see her again until Thanksgiving, by which time the baby would be born. Pattie had to navigate final trimester, premature birth, NICU stay, and early infancy without the sister who’d supported her through summer.

For Susie, leaving Pattie was guilt-inducing in ways similar to leaving Joey in 1995. How could she pursue her education when her sister needed her? But she also recognized Pattie was stronger than she looked, that Ellen and Evan would support her, that Susie couldn’t sacrifice her own future to be Pattie’s support indefinitely. It was same lesson Greg had taught about leaving in 1995: you can love your family and still pursue your own path.

Fall 1998-Present - Evolving Relationship:

After Lila’s birth in October 1998, Susie and Pattie’s relationship continued evolving. Susie likely visited when she could, watched Pattie become a fiercely devoted mother, and saw her sister’s strength manifest in caregiving for Lila. The sisters who had seemed so different found common ground as disabled women navigating a world that assumed they could not be capable—Pattie with ADHD, and Susie with undiagnosed autism and eventual burnout from constant masking.

Public vs. Private Life

Publicly, within family network and school contexts, Susie and Pattie represented opposite presentations of disability and competence. Susie was the “good child”—academically successful, socially appropriate, responsible and capable. Pattie was the “problem child”—constantly suspended, physically aggressive, unable to control impulses. The contrast made Susie look even better and Pattie look even worse, reinforcing stereotypes about “trying hard enough” and “choosing behavior.”

After Susie eventually received an autism diagnosis, the sisters had clearer language for how different neurodivergent conditions and support needs had shaped their childhood roles. Susie’s masked presentation required exhausting performance; Pattie’s ADHD-related impulsivity and dysregulation made her vulnerabilities visible and frequently punishable.

Privately, their relationship was more complex and loving than public perception suggested. Susie defended Pattie fiercely to outsiders even while privately frustrated by her impulsivity. Pattie relied on Susie’s support even while resenting being managed. Both loved each other deeply despite—and sometimes because of—their fundamental differences.

Emotional Landscape

For Susie, Pattie represented both deep love and constant worry. Susie admired Pattie’s fearlessness, fierce loyalty, and complete authenticity. Pattie was visibly herself—loud, impulsive, and physical. Susie, exhausted from constant social performance, sometimes envied that freedom even while recognizing the costs Pattie paid through constant punishment and social rejection.

But Susie also worried constantly about Pattie getting hurt. Physically hurt from reckless climbing and fighting. Emotionally hurt from social consequences and disciplinary actions. Hurt from world that saw her as problem rather than recognizing her disability and protective instincts. Susie’s caregiver personality meant she felt responsible for Pattie’s wellbeing in ways that added to her already crushing burden of family caretaking.

Summer 1998, supporting Pattie through pregnancy, transformed Susie’s understanding of her sister. She saw Pattie’s vulnerability, her terror beneath the tough exterior, her fierce love for her unborn baby despite being terrified of motherhood. Leaving in August felt like abandoning Pattie when she most needed support, adding to Susie’s perpetual guilt about pursuing her own life while family struggled.

For Pattie, Susie represented safety, understanding, and someone who saw her as whole person rather than collection of behavior problems. Susie never made Pattie feel broken or bad, even while trying to help her navigate consequences of impulsivity. Susie defended Pattie to teachers and family when others criticized, translated Pattie’s motivations to adults who only saw defiance.

Summer 1998 deepened Pattie’s appreciation for Susie’s quiet strength. Having sister who sat with her through vomiting, validated her fears about motherhood, supported without judging—that meant everything when Pattie felt most vulnerable. Susie leaving in August was devastating loss, though Pattie probably wouldn’t admit how much she needed her sister until years later.

Intersection with Health and Access

Susie is autistic, though her presentation went unrecognized during childhood and adolescence because she masked effectively: high-achieving, socially appropriate, “just sensitive,” or “just introverted.” Pattie’s ADHD was diagnosed during childhood, but her visible, punishable behaviors were still labeled as defiance rather than recognized as disability manifestations requiring consistent support.

The contrast illustrated how disability presentation affects recognition and support. Susie received accommodations only when they aligned with academic success, including extended time and alternative assessments. Pattie received punishments when her ADHD manifested in ways schools found disruptive, including suspensions for impulsive fighting and detention for climbing out windows. Susie’s autism remained invisible until adulthood; Pattie’s diagnosed ADHD remained inadequately accommodated and was often treated as willful misconduct.

Susie’s caretaking of Pattie—helping with homework, talking through consequences, and mediating conflicts—provided informal support that Pattie desperately needed but schools refused to provide. When Susie left for Stanford, Pattie lost that support structure, leaving Ellen to manage alone while also coordinating Cody’s recovery.

During Pattie’s pregnancy in 1998, Susie witnessed her sister completely unable to function without ADHD medications. The executive function collapse, emotional dysregulation, exhaustion—all demonstrated to Susie how disabling ADHD actually was when pharmaceutical support was removed. This understanding would later inform Susie’s approach to medical practice, recognizing that medication isn’t moral failing but necessary accommodation for many disabled people.

Crises and Transformations

April 1995 - Cody’s Suicide Attempt:

Both sisters processed this trauma differently but were equally devastated. Susie held Joey and tried to support their parents, performing strength while breaking inside. Pattie punched a wall and fought everyone, expressing grief through physical violence. Neither coping method was better; both were responses to unbearable trauma shaped by neurology, age, family role, and circumstance. Susie wished Pattie would be quieter and less explosive. Pattie probably wished Susie would let herself fall apart instead of always being strong.

Fall 1995 - Separation:

Susie leaving for Stanford meant Pattie lost her primary translator and mediator. Their relationship had to continue from distance through occasional phone calls and updates from Ellen. Pattie navigated school without Susie’s tutoring and interference-running, leading to more suspensions and increased family stress. Susie worried from Stanford but couldn’t fix things from distance, adding to her guilt about prioritizing her own education.

Summer 1998 - Pregnancy Support:

This period transformed their relationship from “responsible sister manages problem sister” to genuine peer support and mutual respect. Susie saw Pattie’s vulnerability and strength coexisting. Pattie saw Susie’s gentleness as power rather than weakness. They connected as fellow disabled women navigating a world that underestimated them and supported each other through crisis.

August 1998 - Second Separation:

Susie leaving when Pattie was 29 weeks pregnant represented crisis for both. Pattie lost crucial support at worst possible time. Susie carried crushing guilt about abandoning sister who needed her. This separation forced Pattie to rely on Ellen, Evan, and her own capability rather than depending on Susie—painful but necessary growth. It also forced Susie to trust that Pattie would survive without her constant management—equally difficult lesson about boundaries and autonomy.

Legacy and Lasting Impact

As both sisters moved into adulthood and Susie eventually received an autism diagnosis, their relationship evolved beyond the “responsible one/problem child” dynamic of childhood. They learned to see each other more accurately. Susie recognized that Pattie’s impulsivity was a disability manifestation rather than a character flaw and that Pattie’s fierce protective instincts were genuine love, even when her actions were harmful. Pattie recognized that Susie’s quiet strength cost more than it appeared to, that gentle support required as much courage as physical defense, and that Susie’s caretaking came from love even when it felt like being managed.

For Susie, Pattie represented qualities she had suppressed through masking—intensity, open emotion, and complete authenticity. Watching Pattie remain visibly herself despite the punishment that brought taught Susie that being “too much” was not a moral failing. As Susie eventually learned to unmask and accommodate her own autism, Pattie’s refusal to treat visibility as shame became a model rather than a warning.

For Pattie, Susie represented the possibility that quiet, gentle strength could be as valid as loud, physical defense. Susie’s support during pregnancy taught Pattie that showing up consistently mattered as much as fighting battles, that emotional vulnerability required courage, that being helped wasn’t weakness. As Pattie learned to parent Lila and navigate adulthood, Susie’s example of choosing accommodations over suffering became template for her own growth.

Their sister relationship demonstrates that neurodivergent siblings can have different disabilities and support needs while both struggling profoundly, that visibility does not determine legitimacy, and that different expressions of love are equally valid. The responsible caregiver and the protective fighter are both disabled women doing their best in a world that refuses to accommodate them properly.
