Because You Asked About the Line Between Prose and Poetry by Howard Nemerov

Sparrows were feeding in a freezing drizzle
That while you watched turned to pieces of snow
Riding a gradient invisible
From silver aslant to random, white, and slow.

There came a moment that you couldn’t tell.
And then they clearly flew instead of fell.
