Edwin Arlington Robinson - Tact

Observant of the way she told
So much of what was true,
No vanity could long withhold
Regard that was her due:
She spared him the familiar guile,
So easily achieved,
That only made a man to smile
And left him undeceived.

Aware that all imagining
Of more than what she meant
Would urge an end of everything,
He stayed; and when he went,
They parted with a merry word
That was to him as light
As any that was ever heard
Upon a starry night.

She smiled a little, knowing well
That he would not remark
The ruins of a day that fell
Around her in the dark:
He saw no ruins anywhere,
Nor fancied there were scars
On anyone who lingered there,
Alone below the stars.
