I guess what I look for in a friend is a lot. That's why I have no friends as I would like to have. I usually become bitter for a while, than I call someone up and then feel relief that they still have a friendly word or two. I know and they know I am desperate, and nobody likes desperate people. So I have no friend. Nonetheless I never block people or cease contact altogether. Even non-friends who are abusive psychopaths always get another chance to humiliate me.
