Did a shop, got home and sorted things out, then went to the laptop.
Plonked myself on the chair and oh, ouch, ouch, ouch!
I sat on a wasp and it stung me, It is the first one I have seen this year. I survived, it didn't.
Well let's be honest, it was not a fair contest. A 107kg fat old git versus less than a gramm of wasp. A dab of vinegar and I'm cured, nothing can help the flattened wasp.
