Long ago and far away, I realized a) that I had never, ever, lived in a one-family house before, and b) I was avoiding showering when alone in the house because I couldn't hear anything outside the room. Having a meatloaf of a cat, and multiple ferrets (in their own cage/room) didn't help enough. There was no one to hear me if something went wrong....
(no subject)
I'd never realized that this was a thing.
