What does it mean to be a pushover and what does it mean to be kind?

If someone was a pushover they would do anything that someone asks them to do. In the book Holden is somewhat of a pushover because when Staderlater asks him to write his english paper he does it. When Stradlater got home he got mad at Holden because he wrote the paper on a baseball glove when he wanted to him to write it on something else. He thought it was stupid of Holden when he decided to write it on that.
If you were to be a kind person you would do whatever for any of your friends or family. With how Stradlater asked (well in a way told him) to write his english paper he was taking advantage of Holden. Holden was being nice to do it for him. Even though Holden mostly talks about everyone be a phony, he still is a nice person to his friends when he wants to be. Holden also asked Ackley to go to the movies with him becasue he wasnt doing anything that night, but they didnt end up going and just played video games instead. This was nice that Holden did this because if he didnt, Ackely would have just stayed in his dorm that night and done nothing.
