I was looking after Sam, one of my grandsons, one very hot day. He was thinking about what to do to cool off, so he got a few bodyboards, laid them out on the lawn, then covered them with water and liquid soap. He had been slipping and sliding around on them, and then being a typical show-off with a good sense of humour, he decided to do a headstand. Pretty tricky on a slippery surface! It really was funny to watch.
