She looks like the kind of mildly tarded girl that was brutally bullied in school and at home. I'm not talking any mean child stuff but brutal intentional organized bullying. Even the teachers would join in on it I guess. Most American kids are bullied for being poor. So it's very likely that liv was brutally constantly bullied in not just mean but traumatic severe ways.

She ragequit school and literally went to work. Bet now her bullies all look at her and feel jelly
