Analysis of He's a Poem

You're a poem too
 A couplet, a haiku
 An abridged limerick maybe

You're stuck in the margins
 Of a school paper
 I was too bored to read

I jotted you down
 When I was supposed to compose
 a verse for someone else

But he's the kind of rhyme
 That started in the middle
 And hasn't come back around yet

One I sat down to draft at twenty-one
 And won't finish till I'm hopefully
 Well over a hundred

A real, illuminated idea
 That takes time, revision… a process
 Something I want to write

The next line, metaphor, dialogue
 Ebbing from pen to paper
 Carefully maybe, but easily too

Somehow the pen went askew
 Jotting down scribbles where there should have been
 A resplendent allegory

And now he's a kind of
 ‘To be continued', and I
 Have writer's block
