That's right! Today's the day to print out your favorite poem, stick it in your pocket, and pull it out to show everyone! Poets.org has a webpage devoted to it with a handy-dandy tool to print out a pocket poem of your own!
I figured I'd share one of my very favorite short poems. It's called "Oread," by H.D.:
Whirl up, sea--
whirl your pointed pines,
splash your great pines
on our rocks,
hurl your green over us,
cover us with your pools of fir.
If you like this one, you can find lots more by H.D., including my favorite, "Eurydice," at the Poetry Foundation. You can also read other people's favorite short poems by searching #pocketpoem on Twitter.
