We call ours the centaurs who live upstairs sometimes. They’re just some college girls, definitely not disabled or anything. They make just as much noise flying up and down the stairs sometimes. They’re definitely louder than anyone else who has ever lived above or below us. I think they legit do some sort of dance or exercise routine because sometimes it’s very regular, rhythmic. Idk it’s happy sounds. Happy neighbors having a good time don’t usually bother me, no matter how noisy they are. I’m sure I have a limit, but noisy walking and the occasional party isn’t gonna get me there.
