We can hear our neighbours fuck, they can hear us fuck. I used to hear the TV from the neighbour on the other side, until his mother died, now it's really quiet from there. Kinda sad actually. I can also sometimes hear the kids from below us. I really don't mind those human noises. It's just part of living surrounded by other people.
Unless you're my friend, whose neighbours are regularly loudly fighting at times of day where other people are trying to sleep. I've suggested slipping ads for therapy under their door.
My parents always did the "what are you thinking about?" when I was spaced out in my nothing box, and to this day do not understand why this made me angry. a) if I wanted to share my thoughts, I would have done so, if I'm not sharing it's none of your business! and b) you destroyed my sweet nothing moment! That short respite from my always-on brain, lost because you're nosy!
Makes me mad just thinking about. Glad my love doesn't do this (he wouldn't be my love otherwise, I guess).
