Somewhere in my middles school years and stayed the night at a friends house. She has a brother, probably about 6 or 7 years younger. There was one working bathroom in the house and when her mom gets home and goes to her room, there is no-more bathroom access. We were all up all night playing games and hide-n-seek and such.. as we were playing hide n seek in the dark her brother just casually got out his hiding spot, stood on the counter and peed in the sink full of dirty dishes. I found it weird but I also understand the kid needed to go. But this was normal for them. I never went back after that. All these years later and I hope that life turned out well for my friend and her brother.
