First off, last Wednesday morning, I was going across the street from work to pick up my food from Geri's. Well, when I got to the corner across the street, I could hear music cranked up loud, coming from the third floor, above Geri's. I could also clearly hear two guys grunting, "Unhhh! Unhh! Unhh! Unhh!" (I'm guessing they tried to cover the grunting with the music and failed miserably.)
My feeling is that, if you're going to sit there and have loud sex, don't do it right in front of a window, especially on a very busy public street. It's quite annoying.
It really made me wish I had an elliptical reflector dish.
