For the couple who love the water
Wren, I grew up on boats, so forgive me for saying this the only way I know how. Before you, I was a man reading charts for a coastline he’d never seen. You are that coast. You are the harbor light I steer by and the deep water I’m no longer afraid of. I have watched you weather storms that would have sunk me — your mother’s illness, that brutal winter — and come through with your kindness intact, and I knew: this is the crew I want for the whole crossing. So I make you a sailor’s promises. I will read your weather and respect it. I will never let you drift alone. And wherever the current takes us, Wren, you are my true north, my port, my home.
Why it works: One extended metaphor, drawn from his real life, does the poetic work — no borrowed verse required.
Customize it: Build your own extended image from a world you genuinely know — mountains, music, cooking, the garden — instead of the sea.
