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.
