1. I used to live in a high rise apartment building. One cold morning, I looked outside and the exhaust from all the buildings rose straight up. There was zero wind so all the steam trails were neat parallel lines. I just went to work and didn't take a photo. Now whenever it's cold like today (-9 ) I remember the day when I should have taken the photo. 2. When I was in college I had a friend who had his pilot's license. He was flying into town and I met him at the airport. I was halfway there when I realized I left my camera at home. I didn't want to be late so I kept going to meet him. My last sight of him was as he flew off into the sunset. He died of an asthma attack a couple months later. 3. I saw Ryne Sandberg at Gibson's and didn't have my camera. Now I keep a camera in the car! Do you think about the shot that you should've taken?
