I was on a field trip to a castle. For a wash room there was just an open area with strange shapes. One of them was a three-foot-tall cylinder made of ice, which sort of looked like a sea sponge and I had assumed was a natural phenomenon and that I was supposed to pee on it. I peeing on a cylinder of ice thing and a man coming up to me and talking to me and not respecting my privacy. This really got on my nerves and I stopped peeing and left unfinished.
Although it was a field trip to a castle, the trip was of no interest to me whatsoever.
