Each Valentine's Day I give my wife Rose no card. I write her a poem. I'm a poet, so it seems like the thing to do. She seems to like the idea. I admit it's hard to be romantic in three lines, but I enjoy the form. A signature quality of this holiday is that it occurs in the cold depth of winter (in the Northern Hemisphere).
When the sky is cold,
Our life together is warm,
Be my Valentine.
your misch
(she adds - always, the less than romantic: "Burma shave":)
