Main theme of the "The Catcher in the Rye"

The main theme in "The Catcher in the Rye" is the rebellion against adulthood. This effects the book and the story in many varios ways.
One example which shows Holdens opposition againt the adult world is his relations with other people. Throughout the book his relations with younger are considerably better than the ones with people in the same age as him. The person he bonds most to and has the warmest feelings towards is his younger sister Pheobe. She is still young and inasiant and Holden does everything he can to protect her.
Holden has been kicked out of a long row of schools and his inability to adapt is very distinct. He often finds a lot of people arond him phony because of their appearance and the the way they act. One time he even gets into a fist-fight with his former roommate, Ward Stradlater, because of this.
His relations with people in the same age as him and older are througout the book strained with a few exceptions such as his former teacher Mr. Antolini and a few nuns at the train station. This is something significant for the plot of the book and an important part of the personality of the main character.
