This a bit of my creative writing here.
Is this better as prose or as a poem?
The years. The long years. The sadness of the years.
Or:
The years
The long years
The sadness of the years
If you make it poetry, it’s almost a perfect little encapsulated haiku. If fiction, it would have to be part of a larger work or it could be a three-line microfiction flash fiction story.
