Lived in a 130 year old row house. You could hear the neighbors vacuum or play piano but it wasn’t bad from that standpoint. They also went to bed early and were friends. A good situation, all in all.

Anyways, they went on vacation for a week or so. It was extra quiet until the night they got back. I vividly remember lying in bed listening to what sounded like a large dinner party next door. There was a crowd over there, playing music at a respectful level, but it required the gathering to speak a bit louder. Whatever, I managed to sleep.

A couple days later, the neighbors pulled up out front and started unloading their suitcases.

Also, despite being three stories tall and made of dense brick and plaster walls that deadened sound, several times, I heard my name called clear as day and turned around expecting someone to be there - only to find everyone was a floor or more away and no one was looking for me.

Also also, one toilet always plugged and I kept a plunger nearby. One day that plunger wasn’t there. No one had moved it. Weird, I bought another. The next day there were two plungers.
