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.
