Look ALL ways

My grandfather never owned a car, and so he never learned to drive. He lived about a mile from a small town in Arkansas, and during my lifetime he generally would walk to town sometime during the day to visit with oldtimers who would congregate there. One day, late in his life, as he was walking down the state highway, a car got too close to him and smashed his hand as it passed. After that incident, he told me, "People will tell you, look both ways before you cross the street, but what you really need to do is to look ALL ways." From hard experience he had learned that vigilance is the price of health.
