Agreed. I don't think I'd mind a townhouse though. Sharing walls isn't so bad; sharing floors-ceilings transfers a ton of noise.

My loudest neighbor ever was understandable. It was a shithole apartment built super cheaply. They were above us but their entry was next to ours and then they had stairs that went over our kitchen. Idk the exact situation, but there were like 5 kids around the same age and a young woman who I guess was a single mom to at least some of them, so school would let out and they would stomp and fight and shout for like 5 minutes straight on the stairs. I would straight up just pause my movie or whatever I was doing and wait for it to pass so I could hear again lol. But between the shitty building material and them being just kids and the lady being spread so thin already, I just let it go lol.
