The Yellow Wall Paper.

True story.

I was working at a video store, closing up for the night, and sitting on the counter all of a sudden was a slightly crumbled, stapled packet of yellow paper. No one had been in the store for a good half-hour and I'd have sworn that the counter had been clear.

I look at the packet and it's a photocopy of the short story "The Yellow Wall Paper." Curious, I sat and read it and it scared the hell out of me, made worse by it's inexplicable origins and being the only living person in a closed strip-mall.

I ran to my car and threw that paper into the dumpster before speeding home.
