My Mom called me today to tell me that my Dad asked who she was yesterday. Later in the day, he asked her again, if her name was Marilyn.....which is not close. She told me not to be shocked if he doesn't recognize me or know my name this weekend. My wife doesn't understand my sadness this evening. I told her that today signaled the day every son or daughter fears most, and that the parent I have known all my life may not be the same person when I see him in a few days. Having him tell me the same story 3 times seems so trivial compared to him possibly not knowing who I am. In a few days, I will let him tell me 20 times about his first tractor.............but, God, please let him know my name.
