A day or two before my Mom passed, Mrs Duke and I were visiting her at hospice. Mom was kinda in and out, but in a brief period of relative lucidity, she said to my wife, "Is that your Dad I see? I think it's him, he's waving at me.....with two hands."
Mrs Duke was cleanly stunned, and choked up. Later she told me her Dad always waved with both hands. It was a family joke based on the closing credits of "The Beverly Hillbillies" where Granny was shown frantically waving goodbye with both hands. My wife's dad died three days before I was to have met him, and of course my Mom never met him.
