OK, so tonight something really odd happened and I'm not sure what to do. There was a bunch of odd noises coming from my neighbors yard, not like the normal pool party noise that I'm used to. So I went upstairs to the one window that has a partial glimpse of my neighbors yard. And I saw something that shocked me. It was my neighbors high school daughter with a group of friends having group sex. Do I tell her parents? Do I talk to her directly? Or just let it go... I was shocked to see this.
