I don't have any friends.
My definition of a friend is a person who will die for me and I will die for them. I'm not going to die for them, which is why, based on my definition for what a friend is, I don't have any friends. If someone will die for me they will just die for me. Having a friend that is dead has no practical value.
Sounds a little cold I know...but it is practical. What this means is I make sure my interaction with people is constructive...friend or not. That is usually the interaction people expect from friends but they can get it from me and they don't have to even know me. Help help Borthers and they help me and our interaction is constructive at all times or our interaction is non-existent at all times. Simple.
