Nothing lights my short little fuse like someone taking a candid picture of me. If you do then you've got two choices, 1) Delete it or 2) risk losing a friend. If it ends up on Fakebook you're probably don't get a choice. All the people who know me know this. The ones who don't learn quickly. If you ask politely you may or may not get one. Don't know why but it's one of then few things that will get me in your face.
