I still find each day too short for all the thoughts I want to think, all the walks I want to take, all the books I want to read, and all the friends I want to see. ~John Burroughs, American naturalist and nature essayist

Today is my birthday — I’m finally four!
Too late for Mama to show me the door!
I’ve barfed and I’ve pottied all over her floor,
But one thing’s for certain: I’m never a bore!

Today’s my birthday — it’s all about ME!
I’m just as happy as happy can be.
Cats and squirrels, you’d better all flee;
Guarding and chasing are fun for Monkey!

Today’s my birthday — let’s celebrate!
You bring yourselves; I’ll host the fete.
Cake, ice cream, cookies on a plate;
Only the best, nothing third-rate.

Today’s my birthday — oh, happy day!
I’m ready to party; I’m ready to bay.
I can’t promise anything but skies of gray;
Still, come to my party and be ready to play!

Note: Poetry form (I think) is quatrains. Could be rhyming couplets though.
