Edna St. Vincent Millay 

If I should learn, in some quite casual way,
That you were gone, not to return again —
Read from the back-page of a paper, say,
Held by a neighbor in a subway train,
How at the corner of this avenue
And such a street (so are the papers filled)
A hurrying man—who happened to be you —
At noon to-day had happened to be killed,
I should not cry aloud—I could not cry
Aloud, or wring my hands in such a place —
I should but watch the station lights rush by
With a more careful interest on my face,
Or raise my eyes and read with greater care
Where to store furs and how to treat the hair.
