h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

You may find this hard to believe - but I am equipped with amazing powers! I am the only person in this house that notices the spots on the bathroom mirror. The only one to see the crumbs and dirt on the floor and the only one to see the piles of laudry, dishes, children that need to be washed! It seems to me that there could be dead bodies scattered all around the house and the other members of this household would just step over them unless they were specifically asked to pick them up!
