A saw is a piece of a machinery that eats wood for people. Occasionally a human hand runs into the saw and the saw spits back blood. No one likes that. It causes a big to do. They shut down the whole production for an hour to clean the blood from the blade and take the owner of the hand who is screaming elsewhere. Now everyone is mad at the saw. They starve him for the rest of the day. Everyone liked the saw when it ate the wood. Everyone was proud of it then. These days the wood comes less and less. Things are slowing down. Days go by without the saw eating a thing. The saw believes itself to be dying. When you make a saw think like that, it will take what it can get.
