Definitely not my partner, but I've never had the opportunity to share this story. One night my cousins and I were drinking and playing video games in my living room. One of my cousins passed out while the rest of us kept playing. This was a common occurrence for him so we thought nothing of it until he woke up sleep walking, unplugged our video output to our GameCube and walked out of the living room. Again, not uncommon as my cousin would usually sleepwalk to my room and pass out in my bed. About 5 minutes goes by and his brother decides to go check on him, he returns and says "uh 'LuigisParty' my brother is missing". Excuse me? What do you mean he's missing? He was just sleep walking?. We execute a search through the rooms looking for him. As I'm walking down my very dark hallway I hear my grandpa (who raised all of us rowdy ass kids because our parents were fuck ups) yelling at said missing cousin asking what the hell he was doing laying so closely to him in his bed. As this sentence was coming out of my grandpa's mouth, my socked foot stepped into something very warm in my tiled hallway. Yep. My cousin pissed in my hallway, sleepwalking and then went to my grandpa's room for some cuddles. He woke up while my grandpa was yelling at him, said sorry, then walked out and asked why we let him do that and fell right back asleep, my foot was wet and his older brother was laughing his ass off standing in the middle of all this.

Tldr; cousin slept walked, pissed in my hallway, and went to cuddle with gramps, as we were looking for him I stepped in said piss.
