what kind of tone is established in the first paragraph,and how is it done?

Holden Caulfield is our narrator and he is cynical, "If you really want to hear about it, the first thing you’ll probably want to know is where I was born and what my lousy childhood was like". From his first words to us we pick up on his attitude and tone. Often it is sarcastic or filled with hyperbole. He is articulate and has a style to him. His style, however, is dark. At times he is cynical beyond belief, "If there’s one thing I hate, it’s the movies. Don’t even mention them to me."
