Everyone must say “Happy Birthday!” to Mary

It’s that day today.

(she’s the one in back)

You may be curious how old she is, but we’re not supposed to talk about that. I can say that our birthdays are just about exactly six months apart, which means that when I was one year old, she was six months old, or half my age. Using my keen scientific mind, I estimate that that mathematical relationship would never change, and that therefore today she is still half my age, or 31.

I know. That makes me a cradle-robber. But she’s worth it!

    I held off until today so that I could sing the traditional birthday greetings song of my family. Oh…
