Chapters 15, 16 One Paragraph

In the chapter two nuns talk to Holden about going to teach in a school somewhere else and they are talking when Holden gives them ten dollars. They didn't press Holden to give it to them Holden actually forced them to take it which is surprising because he didn't want to pray in chapter 14 because he didn't like the religion thing yet he gave ten dollars to nuns for their charity. I was making me wonder if Holden is a nice guy but he forces himself to be mean and not like the world because that is what he thinks will make him feel better.
