I mean, come on, everyone can hear everything if you live in a building, that's normal... people have fights, they have sex, they have parties, they have kids... it's normal stuff, I really don't get what the big deal is.
But, I've lived in buildings my entired life and maybe I've gotten numb to these things... I mean, I hear them all the time, but it really doesn't bother me, I just ignore it. Hell, I even lived in a separate room shared household for about a year. I could litelarly hear everyone's converstaions... never bothered me, it was just noise.
