I still love (now) how when I lived in a bottom floor garden apartment, the upstairs neighbor had a piano and he only seemed to play it after he and his girlfriend had. . . gotten it on. So, I'd be awake(ned) in the middle of the night (we're talking 2:00 a.m. or so) by them getting it on (their bedroom was over mine so the bed banging around woke me) and then there would be loudish piano playing, in case I slept through the first? I mostly was across the street at my now-husband's apartment but, when he was away, I'd stay at mine. I made the whole thing bearable by imagining me going up there in my flannel pj's and knocking loudly on the door, having him answer and my saying something like, "I don't mind the good sex but the piano playing has got to go!" and then just turning around and going back downstairs.
