As the smartest boy in school and a prodigy, everyone expects Ian to be a high achiever--a future Nobel Prize winning genius. But he doesn't want to be the next Einstein. He just wants to be a makeup artist.
I have mixed feelings about Ian "giving" up. I mean, he never actually just up and told Allison what was going on. He was waiting for her to figure it out, which she did. She just hasn't told him. But is that a reason to give up on the girl you really like?
