Send us messages when someone adds us as a friend
It may not matter much right now, but it feels odd that someone could add me as a friend without my knowing it. I'd suggest at least sending a notice about it, and perhaps allowing us to approve the friend request (some of us just aren't as social after all)

I favor this one myself, although I do go on an adding spree, I do always think about being kicked, and in that case I know to leave them be, but without knowing if they didnt want the friend add to bother them would seem cruel.
