Much more fun than with mirrors is with a piece of glass.
With glass some light pass trough (is refracted), some light is absorved and some light bounce back (is reflected), the amount of each case depend on the glass material.
The question is:

• How does a photon know that it must pass through the glass or be reflected?
• How a photon knows what did the previous photon to meet the requirement, for example, 90% transparent glass.
• God is playing dice, again?

Much worst, what happens also depend on the incidence angle. For some angle all light is reflected and none pass trough, a window turns into a perfect mirror.
And for other angle none light is reflected. The glass is the same, its material is the same, but how the glass behaves, change.
How a photon knows what to do and how can we calculate what it will do. ????

Stupidity also evolves!
