It happens to everyone at least once - right?

I decided one day to go down to a part of the city that was filled with people. People distracted by other things so they might not notice me. I had my camera, and I was determined to invade the space of others to capture a piece of their world. A camera pointed at me is somewhat unsettling. So after I had turned the camera on myself for several rolls I thought it justified to now turn it on others. The opportunities were rich. A person eating by a statue of the starving Ghandi, a homeless man lounging with a view of the Bay Bridge, a lady with a fabric flower pot on her head - that's right folks fabric flowers and all (She was spotted all over the city that day). I am happily snapping away, cringing slightly when I snap a picture as someone walks in front of me, or missing the perfect pose when someone moved their hand. And then I reach frame number 38...39...40...obviously something critical was missing in this arrangement.

Lesson learned? Enjoy each moment as it is because you won't be able to take it with you? or maybe it is more simple than that...remember to put the film IN the camera!
