I understand why you should not read this for the first time as an adult but my education was neglected in my teens, obviously, since I did not read it then. Holden is a pain where the sun don't shine. He is so whiny. He acts as if he's seen everything, done everything, and knows everything but, as an adult, I want to shake him and tell him to wake up and look at how good he has it. He is the epitome of the angsty teenager who can get on an adult's nerves. He is never responsible for his actions. It is always someone else.
I have enjoyed Salinger's works in the past so I am glad I did not read this one first. I may not have read any more of his works. Although in fairness, I should have read this as a teenager to truly appreciate Holden. It lost something in the last 40 years for me.
