Watching kids play sports is one of life’s most beautiful sights.

I’m not talking about serious pursuits with which I am intimately familiar. Serious pursuits can be an amazing experience, but they are too intense, expensive, and often too exotic. My daughter is a tennis player, my teenage son is also a tennis player, recovering from an injury, and my oldest son is a runner, going through a difficult track season in his final year before college. My youngest son, one of the twins (I have four kids if you’re keeping count) swims and recently started enjoying basketball.
