Bullet hole

While painting Allyssa's new bedroom, we discovered a BB hole in the window. Not to worry, I thought, this was shot from the inside. You see the divet was on the inside, so I thought that was where it was shot from. Not so. The divet is formed on the opposite side of the shot. So it was shot from the outside. So much for thinking that one of the previous owners of the house had a child with a BB gun who made the hole. I hope that it was years and years ago, but there is no way of knowing because the room has been a guest bedroom for over 20 years at least, so even the previous owners probably wouldn't know that there was a hole in the window.
