What is one thing you dislike about your house or apartment?

Relatively new neighbors who walk on the roof. I live on the top floor, a decision I made for both the view and because I didn’t want anyone walking on my ceiling. It’s a really old building (1915) so when someone’s up there it sounds like they could come through the roof any moment. I try to avoid complaining about anyone, but I’ve already asked them not to (they have cut back).
I really hope they’ll move.
