It happens in books alot - I read a book by some asian man, cant remember what its called but it was about him on a gameshow and he got all 10 questions right and because he was poor they locked him up. Basically he stayed with this woman and she killed herself and they found her half decomposed. And i did a really bad job of describing but i might come back and make it better ... maybe not.
Ok well guess what - I think that corpse on the sofa was basically the body of a hippy and because hippies are dirty smelly junkies his buddy probably thought he just toked too much dope and had fallen asleep for 8 years
It's a sign of the times, neighbours no longer know who their neighbours are! If they are constantly changing all the time you would never notice if one suddenly dissappears.
How do you know? You could have gone mad and done it all yourself. You could be talking to them, your imaginary friends. You could have turned them all into finger puppets.... http://www.fat-pie.com/salad2.htm
