My father told me many stories of his mother and her exploits, but he only told me one story about my grandfather and it involved him teaching Dad how to drive a car. During one such lesson, he asked him, “What does it mean when a driver has his hand straight out the window”? My father very confidently answered, “He’s making a left.” Responding to his son‘s innocent answer, my grandfather taught him, me, my children, and I expect generations to follow to cautiously be prepared for the unexpected, by saying, “It means his window is open and that‘s all you know for sure”.
