Using my psychic powers, I precive that your house sits on a ancient indian burial ground. It was customary back then that anyone who walks over the grave of a chief, to offer up some food, to help keep his strengths up in the other world. Your stairs seem to be perfectly crossing his old grave. Hence the spilliage.
Damn, I see that you are lucky, another foot to the left, the stairs would of passed over the chief's wife, which would of made you suddenly jerk off and blow a wad of honor which you must NEVER clean. That might of been hard to explain to friends.
