When I was 10 I was shopping with my Mum in town. We met my new teacher and Mum put on her "posh" voice to speak with her. Half way through a sentence her petticoat elastic went and the petticoat landed in a heap at her feet. My teacher and I both stared down but Mum kept talking then said we had to be going. Took my hand and walked away leaving an embarrassed teacher and a black silky puddle in the street !! On the Monday morning I could barely look at my teacher but she never mentioned it. I still get a flush of embarrassment when I think of it.
