During chapter 2, what did Cherry learn about the Greasers? What did Ponyboy learn about the Socs?

Cherry listens to Johnny's story about his beating and she say that "not all Soc's are like that" and Pony boy agrees saying "not all greasers are like Dally (he was acting rude toward the two Soc's) " They both agree that not all socs are the same and not all greasers are the same.
