Wow! I'm almost the same age as the Rotund Tudor! (Just a month older!)
My wife's family is chock-a-block with birthdays around Christmas. Her Dad is 12/24, her Mom is 1/1, her brother is 1/4, and her oldest sister is 1/5. (And my Dad is 1/3.) Talk about getting a card and not much else on your birthday...
Happy Birthday, sir!
