I tend to dislike confrontation, being a fairly extreme introvert. However, I love watching and photographing people. People are beautiful (even when we're ugly), but I still don't like having to face angry ones.
A few times, a potential subject would ask whether I was taking their photo, and I'd tell them "I'm just waiting for you to get out of my shot."
Discretion being the better part of valor, and cowardice being the better part of discretion, I valiantly hid in the closet. (Douglas Adams misquote)
