Sarah Orne Jewett - Missing

You walked beside me, quick and free;
    With lingering touch you grasped my hand;
Your eyes looked laughingly in mine;
    And now—I can not understand.

I long for you, I mourn for you,
    Through all the dark and lonely hours.
Heavy the weight the pallmen lift,
    And cover silently with flowers.

Sarah Orne Jewett
