"Where you live and who your parents are may affect your future." I believe that this is a true theme for Rumble fish, because Rusty grew up in a bad neighborhood without a mother, and when he grew up he got arrested and put in jail.
"Life is unfair" Rusty and his brother aren't as fortunate as others. They get into bad situations.
Action: Rusty said that only he was aloud to beat up Steve. Trait: He cares about him.
Action: Rusty's dad said that TMB wasn't crazy. Trait: Rusty's father cares for his children.
I liked this book a lot more than I though I would have. It has a lot of unexpected moments and cliffhangers. I got really into it, even though I didn't think I would. If this book had a series I would definitily read it.
