I just responded to another thread, and it brought up an interesting question for me: how does everyone here define friendship? I define it as a solemn (if unspoken) oath to always be there for someone, without question. A friend is someone for whom I'd walk through fire, and who'd do the same for me. Obviously, not a very inclusive definition. So, how does everyone else do it, is a "friend" anyone who hangs out with you, and you enjoy spending time with? Are there levels of friendliness?
