That reminds me of an old old story of a rich lawyer having a flat tire in front of an asylum with one of those very high fences to keep the inmate in. In addition to his tire being flat he had lost two lug nuts. He stood there totally clueless as to what he was going to do to get on the road again. Finally one of the inmates watching the lawyers desperate gestures told him he could fix it. The Lawyer says "How". Easy says the inmate. Just use the three lug nuts that you have skipping holes so you have enough to keep the tire on driving slow into the nearest station and buy new lug nuts there. The lawyer asked him "Why are you back there if you are that smart?". "Well" replied the inmate, "We are crazy not stupid".I do know chronic pain can drive a person nuts.
