Party Invitation

Dear friends, neighbors and distant relations,
we hereby extend our sincere salutations.
You've now received one of several invitations
to a party with friends, games, and decorations!

It's Calvin's 4th birthday, you'll be happy to hear,
and he'd like you to watch as he ages a year.
He might grow a foot, though probably not,
as three feet are one more than most people got.
He might sound all deep, like a grown man might be,
but I think he'll just sound like when he was three.
He might grow a beard, like a real mountain man,
Or flash his gold teeth and a seasonal tan.
He might drive a car, or pilot a plane.
He might be so old that he'll need a cane!
One thing's for sure, and is plain as can be.
Calvin's turning four, and will no longer be three.

So please join us for what needs no explanations,
no allegorical, metaphorical, categorical complications,
no borin' or foreign or complex translations,
but one of the year's most bestest celebrations!
