The catcher in the rye (chapter 4)

In this chapter Holden discovers that Ackley and Stradlater are not to different. He tells us that Stradlater was more like a secret slob in his personal habits. This shows us that even people how seem to be different can have some things in common. Later Stradlater asked Holden to write a composition for english. Holden doesn't gave him an answer, which shows he was not to enthusiastic about it. Later on Holden and Stradlater started talking about Stradlater's date. Holden discover that it was a girl he knew pretty well. That girl was Jane Gallagher she used to live next door close to Holden's house. This is important because it the first time we can really tell that Holden cares or is interested in someone. Probably it was because he likes that girl we really don't know.
