photographic memory

I've started taking photos of things and then never looking at the pictures. It's not intentional, I don't think, but it's something that sort of worries me. I'll see something and capture it in photo--the place where the plow just drove down our useless little side road, just as a car is driving through; some interesting items in a store; some signs that caught my eye at Harvard Square. It's not something I look at later for my own enjoyment. I usually just delete them all when the camera is full. But I always remember the picture. It stays with me. Sometimes I tell stories about how I took a picture of it later, like somehow that makes it more real.
