Regarding Semblance

Mirroring is always,
Very nearly always,
Interesting. Mirrors

In the wild are largely
Symmetries. Actual
Mirroring, reflections

Throwing waves exactly,
Or nearly exactly,
Back at the observer

Are just as beguiling,
As informative as
Symmetry, but rarer.

This obsesses artists,
Obsesses awareness.
What is in the mirror?

If your story has pairs
That mirror each other,
What is not’s the answer.
