Darkening Windows

They have to and will,
And then they’ll turn light.
You can mess with them

With electric lamps,
Throw on indoor lights
Before it’s quite night.

You can close the blinds,
Adjust drapes, place chairs
And tables that block

Or catch and shadow
What the windows do.
But the windows, glass

Whole or broken or
Never installed, will
Darken in some way

Even in urban
Glaring walls of light,
Darken every night.
