In the last couple of decades photography has been divided into genres, and people are encouraged to pick a genre and stick to it. When I was developing as a photographer there was just photography. Sure there were subjects, but we didn't restrict ourselves to any particular genre. I still don't. I was in San Diego in 1977, wandering around with my camera not really knowing where I was. I still don't know where this was but the painting on the round structure attracted my eye. While making the photograph these kids ran into the scene just as I made the exposure. That annoyed me, because I felt they spoiled the shot and film/processing was expensive. So I made second exposure without them. It wasn't until I had the film developed a few weeks later that I saw what serendipity had given me and I was grateful that these kids were there.
