Years ago, while in the bathroom I heard moans and groans coming from the house next door and when looked out the bathroom window, there was the young guy who lived in the house doggie styling his girlfriend, no shades were down and the windows wide open.
My little kid's room was next to the bathroom so I went into it and turnd on their air conditioner so they couldn't hear what was going on and later in the week, when I saw the young guy in his backyard, which was adjacent to mine, and I took the bull by the horns (no pun intended - ha...ha...ha) and told him what I had seen from our bathroom, told him the location of our kid's room and ask if he would keep his window shut and shade down when he and his girlfriend were going to go at it hot and heavy because I didn't think my 4 and 6 year old were ready to understand the sex act. Never had the problem again. The guy did marry the girl and my wife and I would see them around town.
