It’s amazing how after all these years you still aren’t showing your age, uncle! It’s equally amazing that you haven’t started to act your age yet, either!
I’m not complaining, though! I probably couldn’t have an uncle who’s more fun than you!
Many congratulations to you on this very special birthday of yours!
Of course, we all know that the big birthdays are every decade or so, but the truth is that when you get to your age every year is special and cause for celebration!
