the problem is that there's oversensitive people and you actually do impact their lives by being a nurse that comes home at 3 am.

if you cook some dishes, and some oversensitive person doesn't like the smell, then you're impacting them.

it becomes not so simple, especially when you are a building manager and two people have a problem with each other. it's not always easy to figure it out.

Then you have cases like a once per year loud birthday party. That's annoying. Are you really the problem if you do that once a year?

I can hear my neighbors televisions regularly. It's annoying yet I never thought they were a problem. However, another person in the building DOES think they are a problem. Partly because they don't understand that they need to compromise because the walls are so thin. Since the sounds are annoying, do they get to stomp around all night and get revenge with machines and devices? at that point, the petty revenge is probably the problem.

and for a building manager, it's not always easy to figure out which person is the unreasonable one.

Maybe but this is not what the issue was here.

Playing loud music, tv is not acceptable. Or smoking outside that impacts others.

Is your want to do that, live alone in a forest.

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
