Untitled Poem

“‍Good evening, sir‍” the guard’ll say to you,
  Evidently fooled by your disguise.
You’ll nod and pass, in hopes that’s right to do
  And that your nodding won’t cause him surprise.
Then, once inside, you’ll doff your wig and cape
  And look about for that one unbarred vent
Through which you’ll crawl, and thus make your escape,
  Satisfied that none know how you went.
