What effects do the events have on a particular character's life or personality?

In The Catcher in the Rye, by J.D. Salinger, many events that take place result in a juxtaposition in his life or perspectives as a character. For an example, when Allie died, this dramatically changed his life because he had nobody else to go to but his sister. This juxtaposes Holden's life because he develops depression leading him to bipolar depression. This changes his life because he feels tremendously desperate, like when he asked the cab driver for a drink at the bar or when he needed to give his sister back his money, so he could talk to her.

This changes his personality because he becomes a much more lively and social man because he starts talking to people. An example of this is seen when he goes to the Lavender room and sees the three women, who he thinks are a but phonies, but he still talks and dances with them. This helps Holden in a positive way because he gains a sliver of self-confidence which boosts his self-esteem, helping him communicate to people.

In the beginning of the story, Holden makes a huge decision to leave Pency Prep so he could try to better himself in his vision. This shows dramatic irony because holden is blinded by his thought that he will escape this, but really he won't. Overall, this huge step in life to leave his school effects Holden's life because he will not grow up with maturity as if he stayed in his school and will not succeed to his full potential if he stayed in school.
