Their foot steps sound like they just have 2 pegs for feet… they hit so hard.
And they frequently, almost daily, spend the entire evening stomping around the entire footprint of their apartment.
Are there people who really just get the top floor, and think “I’m so smart, and everyone else can get fucked” then proceed to make all the fucking noise in the world?
Maybe they are exercising indoors? Or just have some sort of manic energy they are trying to dissipate.
I guess OP will never know. There’s no possible way to know what his neighbors are up to. Too bad it’s hidden knowledge that will never be revealed.
