Mr Mushroom, and two boys wearing paper bags

We're at the Abergavenny Food Festival, where there is a great number of people and a great deal of food. And, blessed relief from all the conspicuous over-consumption and silly expensive gastronomic treats you didn't know you wanted (and realise you didn't when you get home and try them), there is a craft area, where this gentleman was turning wooden mushrooms at his lathe. Two boys watching were wearing paper bags on their heads. I wish I could tell you why, but I haven't a clue. It wasn't raining, the sun wasn't beating down on their poor brains.
