My son is in year 7. So my child has sports day outside today in the sweltering heat. Drinking lots of water he asked if he could go to the toilet, the teacher who he hasn't spoke to or seen before said no he can wait, he didn't complain he waited until there were a few of them that needed to go and the teacher gave my son a 'key', a kind of card to access the door for them to go in.
He said "don't lose it or you're a dead man walking." My son wasn't bothered about the way he was spoken to (which he said was grumpy and wasnt said in a joke way) and shrugged it off but mentioned it in conversation, I just think it's an odd thing and unacceptable way to speak to a 12 year old as a teacher.
