It’s an old WWII-era building that has unbelievably thin floors, and the upstairs unit was of course cheaply renovated and they removed the carpet and put down laminate flooring. When the couple first moved in, they would wake me up 3-5 times a WEEK for 6 MONTHS. It was insane—they literally only seemed to sleep for 4 hours a night between 1am and 5am. I tried talking to them (they refuse to answer their door), I left pleading notes, I offered to play them vids of how loud it was in my unit, I offered to buy them sound-dampening rug mats for their HOA-required rugs shipped straight to their door—nothing. Finally I went up one night and banged on their door and screamed that I was calling the cops and reporting them (for the 1 millionth time) to the HOA and manager. Then every time they were loud past midnight in their bedroom I would pound on the ceiling for like a full minute. They finally shut the fuck up last year after a week of my crazyass behavior. This was a return to their “normal” (see; psychotic that they don’t sleep) behavior. Triggering.
