In part 2 of Persepolis, Satrapi is trying to negotiate her way through school and this includes all of the challenges of school work and the pressure to do well to please her parents back home and perhaps fulfill the dreams she has for herself, although she seems a bit lost for a good part of the book. She seems to want to succeed, but she is also concerned with what the other students think of her, so she misbehaves by small acts such as drawing cartoon pictures of her teachers.
We also see he working hard to make and maintain friendships with the girls and the boys in her school. She becomes friends with Julie and from there meets other students like Momo -- the boy who gives her her first kiss. In converstations and interactions with her friends she learns about sex and drug use. She goes to parties and listens to popular music.
She is concerned about her changing appearance and experimnents with different hair styles and dress.
As she matures throughout the book we see her grow from an awkward pre-teen through her teen years and into a mature woman who is finally able to return home, shaped by her experiences in Vienna, and yet Iranian through it all.
