Abt 1965 Have you seen my Screw Driver?

This question was asked often by dad. One day I remember he asked both Doug and me if we had used or seen his screw driver. We both told him no because we had not used it. Later that afternoon dad walked in the house with a bent up screw driver and asked again if we remembered using it that day. It was a miracle; we then remembered using it to fix something out in the back yard. When he was cutting the lawn, he discovered it because it flew out of the discharge like a pretzel. Good thing no one was standing near.
