When I was a little kid my dad had a cabin in the mountains. It was real rustic and had no indoor plumbing. We had an out house out back in the woods. It had a big tank under it that would get pumped out a couple of times a year.
At night I would have to walk out through the woods in the dark. By the time I got to the out house I was totally creeped out. Then I'd have to sit there with my butt hanging over that deep dark hole. I was certain something was going to reach up an grab me.
I still don't use out houses. One day you'll see. The is something that lives under there in that tank. It's big, bad, and ugly. By the time he has a hold of you it will be too late. Then whose going to be laughing.
