What would a perfect glass mirror be?

Perhaps perfectly polished
Without a single speck of dust, dirt
The image crystal clear
A view so unhurt

Maybe made magical
Able to show you what you hope, wish
I ask it what I seek
A dream so foolish

Conceivably cannot create
This ideal of perfection
Because in the end
No matter how polished
No matter how magical
A perfect glass mirror
Only reflects perfectly
What is in front of it

Broken imperfection
