Why Ponybpy is a Dynamic character

Ponyboy changes a lot in the story. He changes the way he thinks about things and starts using his head more. He goes from, 'the Socs are so bad, we have nothing in common, they're horrible people blah blah blah', to, 'they're regular people just like me, they aren't that bad blah blah blah'. He starts thinking Randy is just a normal guy, with normal problems, just like him. Ponyboy also changes his mind about fighting in the rumble, because someone could've gotten really hurt. And he couldn't risk it after what happened to Johnny. I really think he starts changing his mind more because he starts thinking more. In the beginning he had trouble thinking right on the spot, but now he's like BOOM I'm smart, and I can think fast.
