The apt we lived in was made of wood frame, so anyone walking above our unit would make squeaky noise. I understand that we couldn't expect our upstairs neighbor to not walk, but he would walk every night starting from 10p to 2a. It wasn't just walking periodical either, it was constantly walking back and forth from one room to another. It could be his dog, but the squeaky noise was so loud that it couldn't be caused by a 30lb dog.

One night it was particularly annoying with back and forth squeaky for 3 hours straight. It kept me up til 1am. I finally had it. I opened our patio door several times (facing in a way that only our upstairs neighbor could hear.) I then tapped on all the vents (mounted high by ceiling) where only he could hear. I did that for several minutes-opening and closing patio door then tapping the vents. Finally he got the message and the walking stopped. I thought he probably slept in the day since the noise always started so late. The next morning I started tapping all our vents after kid and hubby were gone, then slammed every interior door as I walked by (making sure not the one by my side neighbor.) I blasted loud pop music all day. No more night walking since then.

Petty, yes. Effective, double yes. When I am tired, I am cranky, when I am cranky, I slam doors.
