Reminds of those two brother bachelors in NYC years ago, who were found dead in a house littered with boobie traps and filled to the attics with stacks of newspapers.
Wasn't there a book about that? I think it was called "My Brother's Keeper." What's worse are the people who are just plain disgusting. Just recently in Erie, PA a school teacher was arrested for manslaughter. He had gone on vacation and left his male friend, who was disabled, for a week with no care. When the police entered the house it was filled with garbage, roaches, and rats. The poor "friend", who could not move, was found dead, his body covered with bites. This teacher had lived this way for some time.
