25+ years ago I had a root canal and the orthodontist said I had the longest roots he'd ever seen.
Last week I needed a repair on that tooth and went back. He showed no recognition on greeting me, but as soon as he opened my file he said "Oh, I remember you. I was hoping to retire before seeing you again."
I said "You do mouth surgery. You realize ALL of your patients feel the same way about you, right?"
He almost made it. Retired this week.
