In P6 (so aged about 10) I forgot my PE shorts and the teacher made me wear a pair that were several sizes too small. It was mortifying. Like... classmates weren't even laughing, they were being sympathetic and one even said to the teacher that they were being cruel. When it's too bad for a class of 10 year olds to take the piss, that's when you KNOW it's really bad
. My mum was furious

High school I went through in a state of nonchalance and elitist disregard for anyone not in my immediate circle so I didn't really do "embarrassment". Thankfully I'm not like that any more!
