Historically I don’t like swimming pools, but the joy with which my kids approach the whole affair is infectious, and this morning I found myself enjoying the splashes and shouts of a community pool filled with neighborhood children. A father was in the deep end with his daughter. She struggled to swim from the wall to him, gurgling and gulping accompanying panicked strokes. As she tired, he scooped her up and deposited her back to the wall. The whole thing repeated indefinitely.
