A book on friendship?

[nocheta]

Hello people~ a tough question from a noobie, help me out here. So I'm trying buy a close friend a book on what i means to be a real friend since he obviously doesn't know how to be one. I'm sure there's a whole lot of fiction books out there that's centered around true friendship and all but I'm really trying to find a nonfiction book, sorta like a guildline? lol. A humorous (sacastic?) b-day present I guess. But I guess a meaningful fiction book would be nice as well. Advice anyone? thx~
