A little more about me and how people view me

I am Holden Caulfield. I am a sixteen-year-old junior who has
 just been expelled for academic failure from a school called
Pencey Prep. I am intelligent, sensitive and cynical person. Some say
my voice lacks enthusiasm. I like spending time with my little sister
 Phoebe and older brother DB. He writes books and movies in Hollywood.
 I like going to museums. I enjoy dancing and having a fun time.
I like to spend my free nights at the bar then move on to the dance floor.
 I like taking walks in parks, especially Central Park. I find the hypocrisy and ugliness of the
 world around me almost unbearable, and some feel that through
my cynicism I try to protect myself from the pain and
disappointment of the adult world. They also believe that the
criticisms that I aim at people around me is also aimed at myself
 (how stupid is that?) Some say that I am uncomfortable with my
own weaknesses, and at times I display as much phoniness,
meanness, and superficiality as anyone else, but I don't believe they can be right.
 Though, sometimes feel like I am on the verge of emotional collapse.
