Christie feels like one of the guys at school, she messes around with the jocks and is treated like one of them by everyone, even the coach. she just had a bad break up and she then finds out that a guy that used to (seemingly) hate her in primary school is now living next door. she finds that he is ok now and thinks he was just being childish before and has grown up. they end up spending some time together when both her parents abandon her and she finds out more than she expects from the guy she hated so many years ago and vice versa!
