It's puberty time, but Marjane blows through her awkward teen growth spurt and adopts a new punk-rock hairstyle.
She's still trying to find herself, though. Her friends smoke a lot of hash, but Marjane only pretends to.
She feels like she's betraying her parents, who sent her away to give her the freedom to be herself.
When she tells someone she's French, she feels extra guilty for betraying her Iranian heritage.
It all comes to a head when she overhears people talking about how weird and ugly she is. They see through her lies.
She stands up and yells at them, "I AM IRANIAN AND PROUD OF IT" (24.47). You go, girl.
Embarrassed, she cries at first, but then she feels good because she just stood up for herself. "If I wasn't comfortable with myself, I would never be comfortable" (24.52), she says, which is a really good point.
