Friends are different from family. We choose them and they choose us. Philosophers long wondered about what makes friendship such a distinctive relationship in our lives. Is being a good friend a kind of moral virtue?  Can friends help us find our true selves? What about the dark and difficult side of friendship — toxic friends and frenemies? How is the love between friends different from romantic love?
