Explanation:
do u think u could tell more on the question then I will answer?
A short story's setting is made of time and place.
Apart from plot (what is going on) and characters (who is doing what they are doing), the setting (where and when is the plot happening) is the most important element of a short story. The interpretation of a short story depends very much on how the author has described the setting. It provides a context for the events.
I would say either a free verse poem or a short story.
Free verse- You are not constrained to a meter and it doesn't have to rhyme. You can get your point across without limiting your thoughts!
Short Story- Your example can be taught in a fictional genre, a non-fictional genre and it can be as long as you want it to be!
Hope this helps!
