In my youth, I had a friend who came every summer to stay with her aunt. We were neighbors and Debbie was about my age so it was only natural to be friends. We swapped nights about and spend many hours at each others homes.
The last summer we were in our early teens. The home where she was staying had two bedrooms with a bath in the hall. Off one bedroom was the living room and off the other was the kitchen. You could travel a circle and cover all the house except the wash room and den.
Deb's uncle was quite a cut up and always like to tease us and scare us. Knowing this, everyone was in a camper playing cards so we locked them in while we went to take our baths. It was a hasp lock and we put a large stick through so it would be difficult to get out.
As we were dressing, we heard some one walk in and stop at the door, we could see the shadow under the door, two legs and we could hear breathing. Just knowing that it was probably Dub, we whispered and made a plan to jump out and each circle a different way to catch him at his tricks. We jerked the door open and ran the circle...no one!
