My grandmother used to tell us grandkids a story about an elderly woman's ghost who kept the front porch of her house swept clean of leaves after she died.
Don't fuck around in old houses, no kidding. There are lots of awful fungal infections you can get. Some years back, Zhou Fang inhaled some spores cleaning out the attic for his sister, and he almost died from it. He's okay now, even if he never posts here anymore.
