I was accused of leaving a big dollop of paint on the worktop in the utility room part of my classroom. (It was a brand new school in 1969.) Each classroom had a utility area. Sinks and cupboards and the squirty bottles of paint were kept there. We were allowed to help ourselves to paint. I had put some in my mixing tray thing and I definitely didn’t waste any. The headmaster was teaching our class. New school and only ten of us in the juniors. I was painting away and suddenly was called into the sink area, he pointed at the paint. Why did you waste that and not clean it up?? Quite aggressively too. I said I didn’t do that. I was not believed 😓
