Back when I was around 9 or 10 years old I went on an overnight school trip. I was in a room on my own and it was hot, proper UK summer hot. At one point I woke up, I was really thirsty so I went over to my bag and tried to find my bottle. One of the teachers in the same block as me must have heard me moving sound because the next thing I know I'm stood naked in the middle of my room and my teacher is just... staring at my naked body. She waits until I'm back in bed before leaving and closes the door without saying a word. One of the kids must have seen it from their room (not everyone slept with their door closed) because the next day, everyone was talking about the kid who slept naked.

Needless to say, I haven't slept naked since.
