No, I'm not remotely suggesting that's the story Arya. I'm not sure how you took that from what I said.
I listened v closely to what he said, as I was disgusted with what I read on various sites yesterday, and had a bit of a tirade over dinner last night.
From what he said, it appears that there is a school uniform tracksuit. With Covid, children wear their PE gear to school for the full day on PE day- I know this to be true from my own DDs.
My own DDs try to get away with not wearing the uniform track bottoms, so I can imagine something similar in a school that is less than 100km from us.
I am suggesting that the story "grew legs" .
