Write a Short Poem That Actually Does Something

Most AI-generated poems arrive with the same vocabulary: light, breath, soul, journey. This one has banned them. The result has to say something specific, use a concrete detail rather than a metaphor for a metaphor, and stay under 16 lines. A small constraint that produces something worth reading rather than something that sounds like a poem.

Write a short poem about {SUBJECT}. The poem should: say something specific rather than general, use one concrete image or physical detail, avoid the following words: beautiful, heart, soul, journey, breathe, shine, light (as metaphor). It should be under 16 lines. Tell me in one sentence what you were trying to do with it.
