I'm 54 and I'm a Teen in a Small Town in Central Virginia

As a teenager, i lived in a small town in central virginia. One of my best friends, chris, lived across the street from a peculiar house. Over the years, kids had thrown rocks and broken every window in the house. This old house had vents built into the floor so that heat from the downstairs would float up through the vent upstairs. As we heard the footsteps crushing glass directly below us in what used to be the living room, we carefully peeked through the vent to try and see who was downstairs. With the footsteps directly below us, we could see no one downstairs. Then suddenly, the footsteps were upstairs, at the top of the staircase, right outside the door
