Let's play harder and move to Haiku. The form pushes writers into simplicity and into SEEING current detail. 1)Haiku usually addresses--in the moment--nature or seasons and seldom uses metaphor.
2)The more simple and close to perfect observation the better.
3)Seventeen syllables; three lines; five, seven, five.
4)The first line usually names the subject and other two lines illuminate with concrete sense detail.
Like I said, the more simple the better, though you can stray from nature once in awhile as in example below.
Matt's useless detail:
"Girl sits on lawn with rolled-up pants.
Cute." Matt walks on by.
But, nature haiku are better--
Moon rolls through storm clouds
If I could catch a moonbeam
tonight, I could fly.
Moon moves through white clouds.
I could reach and catch the moon.
Tonight, I will fly.
(Whoops. Too close to metaphor)
