I seem to be on both sides of the fence on this one. I use to live in an old house that was changed into apartments. My neighbor use to tell that it was the bass. I liked to party and I would have people over late at night. I would tell them that they really could not be loud and to please please please be considerate that it was late and that my neighbor downstairs was sleeping. It turned out it was his downstairs neighbor who was being loud. Paranoia... Now, I live across and next to people who are really loud but...eh, it is really annoying but it is not stopping me from living my life.
