My son's nursery cancelled his sports day after the rain for safety
reasons. I asked why and was told that the children might fall on the
wet grass. Children fall over at that age anyway - fact. I explained
to them that falling onto soft wet earth was safer that falling onto
hard dry earth. It finally turned out that the staff didn't want to go
out onto the wet grass. In fact nothing to do with safety.
Why can't folks just be honest and say (here) that they're moving to
the runways to get off the mud.
