On June 7, 2014, I went out to play tennis. As I started warming up, a woman with two preteens started practicing two courts down. She shouted instructions and compliments to the boy while the girl hit off the backboard. After about 10 minutes, Will, my tennis partner drove up and called to me from outside the courts. He said he had a present in his car for me. He raised a tennis basket in the air—one of those metal cages for carrying lots of balls. I shouted back that I already had one. But then the woman two courts down shouted that she needed one. She said she was going to buy one today to help teach the kids how to play tennis better. Nice fit.
We know they happen. The data are very clear. Coincidences appear in the lives of most people, some more frequently than others. We can describe them in terms of mind and thing. We can list their archetypal themes. How can they be used?
