I shot an arrow into the air,It fell to earth,
I knew not where;For so swiftly it flew,
the sightCould not follow it in its flight.
I breathed a song into the air,It fell to earth, I
knew not where; For, who has sight so keen and strong
That it can follow the flight of song?
Long, long after, in an oakI found the arrow,
still unbroken;And the song, from beginnning to end,
I found again in the heart of a friend."

-Henry Wadsworth Longfellow
