Mr. R. could be described by some as being a "grumpster."
He's 92 and he's got a full head of white hair.
He hit me with a few zingers the last time I went to visit him.
My favorite was the following:
"You look as old as I do. What can you possibly do to help me at your age. Can't I be seen by a younger doctor?"
I'm only 52, but in his defense, I also have a full head of white hair.
