Holden is a regular kid that attends Pencey a very expensive only boys school in the United States, though he does not like it very much...
I don`t like it here when I am older I will never put my children here.
Why do you not tell me what you will do with Jane tonight?
After his last day at school they tell him that he didn't approve all classes. Also he gets into a fight with his roommate and he breaks Holden's nose.
I already told you, its none of your business.
When I get to the city I will use my money to sleep at a hotel, then I will see what I will do.
After hesitating it for a long time he decides to escape his school and go to the city. Holden was not going to stay with his classmates that he didn't like if could choose to leave. He had two weeks before he had to go home so he is going to take this for himself.
