I went to watch my son at a mini soccer tournament the other day. It was great fun; watching any member of my bloodline play sport is a joy, and not because we are good. But I’m not writing about that today. I’m writing about pants. While the eight-year-old boys ran around the field screaming at each other like pro-footballers and flailing awkwardly at the ball as if it were on fire, I noticed another group of boys on the side of the field. They had found themselves a grassy embankment, and were sliding down it on their knees. It looked like fun.
