This is an exercise for learning how to be descriptive in an artistic way.
You may choose an event to center this poem around; its currently autumn, so maybe use that! I'll help you get started.
I see vibrant leaves fallen on the street
I hear the wind blow them, scraping the pavement as they take flight
Because the planets have to be aligned just right for it to happen
Based on the definition of appositive, this is a noun or noun phrase that is used to rename the another noun beside it. Basing on the given sentence above, I believe that it does not have an appositive. The nouns are Joe and Tulips, but no other noun that renames either of the two. Hope this answer helps. Have a great day!
