What Left With the Light

A hundred-nanometer bead of glass held up by light in a warm room.

One beam keeps its shake quiet. Another lets the shake ride out with the light that leaves.

The bead stays. The room stays ordinary. Only: in what went away, the motion is still written —

not as a message meant for us, just as the fact that after the light left, there was no clean account of glass alone, or light alone.
