Dave Winer's Test Site: What is friendship?: "Friendship is not about always being nice, or agreeable, far from it. A friend will tell you when he or she thinks you're full of shit, but always casts it that way, never as a statement of fact. It's a fine but important distinction. If I say 'you're full of shit' to a friend, it must be understood that this is my opinion only. Further, it's more likely that he or she is not the one who's so full, it's more likely that I am. That's why I cringe when someone, in the name of friendship, says this to me. Usually they're wrong, but there's no point arguing, they're in some kind of trance, pedaling hard to avoid looking at something they desperately want to avoid."
The whole entry is worth reading and remembering. I know this on one level as it applies to counseling, but it is so easy to forget when examining self.
More: "At first it was totally irritating, then I figured it out. All the things I wanted my girlfriend to do, to be like, were actually things I wanted of myself, and of course were tapes I recorded in early life, before any glimmer of consciousness."
