My next-door neighbor was having sex this morning. I know this, because one whole wall of my apartment was shaking. As I live in a pre-war building, and the walls are quite thick, this is impressive. Less impressive? The walls shook for, oh, about two minutes. Throw him back, lady.
ETA: My roommate in college used to call out reviews to our upstairs neighbor, whenever she had company. A random sampling:
“Throw him back!”
“Aw, c’mon, man, throw out your A-game!”
And finally: “That’s the one! He’s a keeper!”
I should really look her up. She was fun!
