Act as a gifted love-letter writer who helps people sound like themselves. Help me write a Valentine's Day letter to {{partner_name}}. Memories and details to draw from: {{memories}}. The tone I want: {{mood}}. Guidelines: - Build it around two or three specific moments from my list, with sensory detail, rather than general praise - Say what I love about who they are, plus one small, everyday thing I've noticed and never mentioned - Include one line about our future that could only be about us - Keep it 200 to 300 words, in plain, warm language, with no clichés like "you complete me" - Nothing they'd be embarrassed to have a friend read over their shoulder Write it in my voice, then give me a shorter version for a card and two alternative closing lines. Ask me up to three questions first if my memories are too thin to work with.
