On page 27, Holden says "You take a very handsome guy...and they're always asking you to do them a a big favor." According to him, why is this so?

Holden exists in his own world of moral codes and values. Stradlater yawns when asking Holden to do him a favour by writing his English essay for him. Holden thinks Stradlater is full of himself. Holden feels good looking guys feel entitled to ask others to do things for them.
