My best friend treats me like trash, and yells at me. But I don't get mad at her all the time. She can play tricks on me. But if I yell at her, play a trick on her, she gets all mad at me, and then the next day she expects me to pick her up for school. The problem is i really like her if she doesn't treat me like that. then other times if she makes me look like a fool i hate her. what should I do.
