I love these! I much prefer the spontaneous shots over staged shots. Capturing life, capturing moments--this is for me the greatest value of photography.
This reminds of years ago when I was in college. My best friend was a psych major and had to do 'experiments'. For her the experiments involved catching people unawares in public. She would use me as a prop. We would go into a crowded area--a subway car, Grand Central Station--and she would have me behave oddly. I was supposed to do something that might startle or surprise people. She would record their reactions. It was an interesting exercise. Although, in hindsight, I'd say it probably put me in some risky situations:))
