We Grow Accustomed to the Dark
by Emily Dickenson


We grow accustomed to the Dark—
When light is put away—
As when the Neighbor holds the Lamp
To witness her Goodbye—

A Moment—We uncertain step
For newness of the night—
Then—fit our Vision to the Dark—
And meet the Road—erect—

And so of larger—Darkness—
Those Evenings of the Brain—
When not a Moon disclose a sign—
Or Star—come out—within—

The Bravest—grope a little—
And sometimes hit a Tree
Directly in the Forehead—
But as they learn to see—

Either the Darkness alters—
Or something in the sight
Adjusts itself to Midnight—
And Life steps almost straight.
