One day, when it was nice out and most people had their windows open, a couple decided to have a loud fight in the courtyard, completely oblivious to the fact that pretty much everyone in the building could hear.
I don't remember any of the details, but at some point the girl yelled: "So tell me what you want to do! If you want to break up, we'll break up! If you want to go inside and fuck, we'll go inside and fuck! Just tell me what you want!"
There was a long pause.
Then some unseen guy on the 3rd floor yelled: "Tell her you want to fuck!"
The couple looked absolutely horrified. They got in a car and left.
