It is this feeling that should bind the family so that it can withstand the difficulties of the outside world. Phoebe in the novel personifies angelic selfless and selfless love. Salinger, at the same time, shares a loneliness-ailment and solitude, which is a boon for a person who wants to stay away from society. The author shows how dangerous it is to leave a child alone in such a period: he can turn off the road simply because he had no one to pour out his soul. His acquaintances at school are superficial, and the loss of a brother and separation from his sister weighs his soul. Holden Caulfield does not feel a spiritual kinship with anyone, so it's hard for him to learn and remain calm.
Meeting with her sister brings a little relief she remains, probably, the only person who can at least somehow influence him. Not enjoying anything, he tries to communicate with his sister Phoebe, with whom he had a warm relationship. Trying to fill the remaining days with some kind of activity, Holden goes to bars, meets with former comrades and teachers, but in everything and in all he is disappointed and hates everyone. After quarreling with the fight with his roommate, Holden decides to leave the school a few days earlier than necessary, and leaves the hostel, moving to the hotel. All these lead to the fact that Holden feels very insecure in society and diligently avoids all forms of friendship, good relations. Holden Caulfield finds no interest in teaching and in school activity: he fails four subjects out of five, and he is kicked out of school in a trip to competitions in fencing he forgets the sports equipment in the subway and his companions turn away from him relationships with classmates do not fit, because Holden does not like their desire to seem better than they are, to pronounce what they do not think, do what they do not care and so on.
The narration goes on behalf of a 16-year-old boy, expelled from the school for academic failure.
