Holden
He wears his red hunting hat so that he can be unique, even though he himself thinks that the way he wears his hat is corny, with the peak swung backwards. It suggests that he thinks that people will avoid him if he wore his hat in an corny way, in an unique way, so that he wouldn't have to get connected towards other people so that he can make leaving schools easy, he could've chosen this method of detachment as the last couple of schools he was at could've been difficult for him to leave. This links to theory that he believes he is above other people do therefor he doesn't need to interact with them because he thinks of them as "lesser" people. When he was planning on talking to Jane Gallagher he kept saying that he was going to however he talked himself out of it.
He doesn't want to become an adult so he is always fighting his biological clock, he doesn't want to become old and die as it suggests that he can't imagine he is going to have a wife and kids because he always detaches himself from the rest of the world as he thinks that if he detaches himself from the rest of the world he can prevent himself from growing old that's why he says he is like a child however he always takes responsibility of the fencing team rather well even though he lost the foils on the train as he got loss but took the full responsibility and didn't think of blaming anyone else.
