The road kill secret completely freaks me out.
Last year I was driving to work and the road was closed in the other direction because of a dead guy. He was still lying there, with a sheet over him when I drove by. The road had a stain on it for months. It still bothers me, and I wasn't even part of it. The news said he'd been run over by mutiple cars before anyone stopped. How could you not see a dead body in the middle of the road? How could you drive over it and just keep going? How could you live with yourself?
