I never put that together 'fore. Oh, mister, I beg you. Don't go back to that house. It changes people. It'll change you. And then in ten years you'll disappear too."
I was no longer thinking that what Mo was telling me was hogwash. I don't believe in the supernatural, but I also know there are a helluva lot of things in this world that can't be explained away by science.
