Doc. Such a different experience for you, but Dad and I have not always been "close", if indeed you could say that we are now. Differences about The Viet Nam War, among other things, took a toll on our relationship that will never be repaired. We are rather textbook examples of the effects of "The Generation Gap". I think we both wanted the relationship enough that we learned over the years to just STFU about certain subjects.
Prong. In truth, the actual "hard" part is exactly what you refer to...not letting him see me notice the changes. The chores are just motions. The hard part is performing the chores with finesse and tact.
PhD. I have had this conversation with myself and others, wouldn't it be easier if they would just "hurry up and die." Sometimes, I guess, a long life is not a blessing but a curse. I have no small anxiety wondering what I will do when my time comes. I can't imagine suicide. Neither can I imagine waiting, essentially invalid, days, weeks, years, waiting for the release of death.
Brisket. "...seeing the transition, and the gravity of it..." Keen observation, as usual.
Kenny. Please don't apologize for the "sentimental diversion." I wanted to hear your story.
