I wrote a post last night, looked at it, decided I really did not want to step between the contestants at that time of night and get sideswipes for my pains, and deleted it. If anyone else joins in this infighting and takes sides, or tries to make the participants see reason, they get told by one or other (or both, or by the bystanders) to MYOB.
I wish I had a diary recording the intervals between spats. It seems to be cyclic. For a while afterwards everything dies down and we all play nicely together, then one of gods on Mt Olympus decides it is too quiet and stirs up discord.
