This one was written when I was in college. This is another one that I actually use in my English classes, without telling my students who wrote it. I ask them to look for exact rhymes and slant rhymes, and I have them contrast the depth of meaning with an Emily Dickinson poem.

I Hum a Melody, by Anneliese Kvamme

I hum a melody
   all my own
  a tune I make up
    as I go along,
 And you hum your tunes
   not at all the same
  as mine; they follow
  a different time–
 So we both go on singing
   along with the breeze
  Not noticing we create
      harmonies–
