Hey, I think I know exactly what you mean regarding the defriending issue, because I feel the same. "Is it my bad grammar, was my last post insulting, did they look over my recent entries and later decided I wasn't keeping up the standard so I was fooling them somehow..."

So I never defriend someone unless they defriended me first, and then I do it quickly. I have no problem with friending someone and not being friended back, but defriending seem's so... ...rude.
