Little Caulfields

Holden cares a lot about his little siblings. When he described Allie he had nothing negative to say about him, and when he described Phoebe there were only a few negatives he had to say. You could hear the love in his words when he described those two. They are truly dear to him, and he can trust them. "You'd like her. I mean if you tell old Phoebe something, she knows exactly what the hell you're talking about. I mean you can even take her anywhere with you." Can't you hear that. He's proud and impressed with her. But he never sounds that way when he talks about D.B. He always says that D.B. "prostitutes" himself, and that he isn't very thrilled about him.
One thing you could infer about this is that he cares about youngsters, and that he looses respect for those older than him. Perhaps he thinks those that are young, are sweeter, more innocent, maybe even naive. Or perhaps he thinks they hold insight that the older folk loose because of all the stress to make lots of money and be successful. But no matter how you look at it, or what inferences you make, Holden loves his younger siblings; Phoebe and especially Allie.
