Here’s a poem by former US poet laureate, Ted Kooser, who sent out 2,700 Valentine’s Day cards in 2007. He has collected those poems in a book called Valentines.
My favorite –
A Map of the World
One of the ancient maps of the world
is heart-shaped, carefully drawn
and once washed with bright colors,
though the colors have faded
as you might expect feelings to fade
from a fragile old heart, the brown map
of a life.
But feeling is indelible,
and longing infinite, a starburst compass
pointing in all the directions
two lovers might go, a fresh breeze
swelling their sails, the future uncharted,
still far from the edge
where the sea pours into the stars.
