TITLE: TIFU by using a toilet when my uncle was fixing the pipes in the rest of the house
POST: So like most people on here I read a TIFU and remembered a similar thing that happened to me. So little bit of context, my father used to have a friend who was quite well off and we would visit and spend time there. So basically one time their downstairs shower was broken in some way so I couldn't use the toilet in there, didn't think much of it just was told go use upstairs so off I trotted to relieve myself, thankfully was just a quick leak. Now I don't know if this was the case but I felt guilty all the same and I was about 12 y/o so I didn't think to ask but basically after doing the toilet I came downstairs to see my Dad and my Dad's friend and wife and all laughing at my uncle who was wiping his face with a towel complaining and giving me a horrible look. I still to this day don't know if that was me or it was something else but the fact they were laughing was fishy...
TL;DR: 
Uncle working on pipes behind shower, can't use downstairs bathroom so use upstairs one. Come downstairs to my Dad and his friends in stitches and my Uncle drying his face with a towel giving me a horrid stare.
