I love this. It makes so much sense. I often will try to rescue or coax along a poem by imposing the order of a closed form upon it. Sort of like "if you won't behave in free verse, I'll turn you into a sestina!" Sometimes there's no going back. Sometimes I end up discarding the structure eventually. But I never considered the possibility that some of my essays might actually be dreaming of being a poem one day. That's really exciting. Thanks so much for the inspiration.
