Our bathroom
You know the bathroom’s going to be gross, so you hold it and hold it until you HAVE to go. But then you have to try and restrain yourself, because the harder you pee, the more it splashes. Choose door A, you pee on poop and deal with the disturbing possibility that poop water could splash on you. Door B means peeing in a hole. That’s fine when it’s not stopped up, but most of the time it’s stopped up which means other people’s pee splashes on you. Incidentally, this is also where you take your bucket shower.
