What does Ponyboy learn about himself through Soda Pop's outburst in Chapter 12?
Sodapop's outburst serves as a catharsis for Ponyboy. He seems to snap out of his depression and is able to think of Dally and Johnnie without overwhelming sadness. His brother's want him to still be the sensitive, thoughtful kid he always was.
Ponyboy realizes his experiences don't have to harden him, that he can tell his story to show that unresolved anger can lead to violence, senseless violence.
