I got told we were like this once. Mle and my wife would literally tiptoe around after, carefully close doors, live in a constant state of worry, and still the next morning the guy below would say "you're literally shaking paintings off the walls!" My wife was physically afraid to run into him after a bit.

At the time I thought the apartment must have paper thin walls that apparently I couldn't hear through, but now I think he was just an ass. Living off self righteous anger.

YMMV. You have situations like the one you describe, and you have situations like mine. There's a unit down the hall that keeps everyone on the damn floor awake. There's a nice dude who lives there and raises his grandkids, and there's also the kid's father. The kids and the grandfather are great. They're respectful, kind, and very friendly.

The kid's father has this "fun" habit of sleeping with complete randos. You do you, yadda yadda. I try to mind my own business.

He makes it EVERYONE'S business. Every single time he gets dumped, he throws an enormous hissy fit. Screaming incoherently, banging on every door in the hallway, stomping about, etc. He doesn't work, yet he throws a hissy fit when he has to watch his own kids because the grandfather has to work. It doesn't matter if it's 2am or 2pm, there's a decent chance that that guy is pissed at something. It wasn't uncommon to see him crying by the front doors.

It's a great personal reminder to never start doing hard drugs. I only know that the guy does hard drugs because of the grandfather was venting to me about it. I can't even begin to tell you how many times the cops have been called on him by other people.

Fuuuck I wish it was cheaper to move.
