Your comment impacted me, so I assume you'll post an apology for this deeply problematic behavior of yours?

Plenty of times the fault is with the apartment, etc.: if the reasonable noise of me living disrupts my neighbors, that's bad design. Different people work different shifts - I don't see why the morning person should have to hold off on a morning shower just because the plumbing wakes up their neighbor, nor why the night-shift worker should have to hold off on doing laundry just because that wakes the morning person up.

Right, I was thinking about avoidable things like playing loud music or smoking in a particular place. Obviously old building and normal usage is a different situation
