Chapter 7 of Catcher in the Rye Summary

After Holden's fight with Stradlater, he goes in Ackley's room, angered by the nights events, and asks to sleep in Ely's bed to get away from Stradlater. Ackley denies him which is why he then goes on to explain how "lonesome and rotten" he feels. But for what? Because his jealousy he has from Stradlater's fate with Jane? For fighting with him? For being turned away by someone he feels so superior to? He goes on to ask Ackley about what it takes to join the monastery and if you have to be Catholic. We can assume he is a defense mechanism after Ackley told him that he needed to leave. That offends Ackley and says he can poke fun and him all he wants but not about his religion and Holden responds with this insensitive and contradictory "Nobody's making any cracks about your gaddam religion, for Chrissake-". He admits to feeling "sad and lonesome" staying at Pencey until Wednesday and makes plans to stay in New York until his parents receive the letter. The final thing he thinks about when he is packing is putting away a pair of ice skates his mother just sent him, "Almost every time somebody gives me a present, it ends up making me sad." I'm guessing it makes him feel sad because he feels like he isn't worthy of other peoples gifts in which they put time, money and effort into. It's getting more and more obvious how insecure Holden really is.
