Have you ever looked at a picture of yourself and saw a stranger in the background? It makes you wonder how many people have pictures of you, how many moments of other people's lives we've been in. Were we part of someone's life when their dream came true, or were we there when their dreams died? Did we keep trying to get in, as if we were somehow destined to be there? Or did the shot take us by surprise? Just think, you could be a big part of someone else's life, and not even know it.
