The gall of it

Some eejit decided that the thunder and rain had stopped, so a walk would be nice. Hah. Luckily, the eejit had a waterproof. The non-eejit didn’t. Who’s the eejit now?

I saw acorns on an oak for the first time in ages. Many had growths. I’d seen them on telly, but couldn’t remember what they were or what caused them. A hole on some of them was a clue to a creepy-crawlie. I looked it up once home and dry: knopper gall wasps (aka acorn gall wasps).
