Rosie, Violence, and Depression

I think this is an incredible moment in the book. It's a well-known fact that children who are abused grow up with the tendency to be abusers themselves. As Tia says, that's what she'd be taught by her mother. However, it also shows that we have free will, that we're not required to end up the way our parents trained us. It also shows that Rosie had a propensity toward depression. Depression has often been called "rage turned inward." Instead of lashing out at the world, she turned her anger in on herself which is why she ultimately had to go into counseling and on anti-depressants.
