What does it mean to be a good person?

For me to be a good person means everything because you can't make very many friends if you are always mean to everyone. In my personal life experinces, it is so much easier to to nice to people you don't like than to be rude or start a fight for no good reason just because you don't that perosn. life moves on and you may not ever see those people again in your whole life, but when you get older and look back at you life do you want to remember those people as your self always fighting with them. In the book Catcher in the Rye Holden is never really happy, he calls everyone "phonies" but mean while he should be calling himself that becuase he dosent know who he is on the inside. Holden has no real friends becuase he never really gets to know people for who they are. Holden just judges them before he even gets to know them and in my opinion that is not right. For me personally Holden is the biggest "phony" tn the book.
