Shadow
A shadow is an area where direct light from a light source cannot reach due to obstruction by an object. It occupies all of the space behind an opaque object with light in front of it. The cross section of a shadow is a two-dimensional silhouette, or reverse projection of the object blocking the light. The sun causes many objects to have shadows and at certain times of the day, when the sun is at certain heights, the lengths of shadows change.

When clouds obscure the sun our shadow flees.

But swift is gone whenever she veils her face.”

And here face downward in the sun
To feel how swift how secretly
The shadow of the night comes on . . .”

I used to be.
There’s a shadow hanging over me . . .
From me to you out of my electric devil....”
