Only a mote...

Only a mote somewhere in the dark.
The sun lights it, but it's invisible, it's lost in the dark that surrounds it. The sun heats it, but it's freezing. Nobody knows from when, but it is. Nobody knows where, but it exists. Nobody is waiting for it, but it's waiting for somebody.
Today I saw what a mote worths when the Earth collides with it, it's running across the sky, and somebody's eyes are reflecting its light for a couple of moments.

Today I was the somebody, the mote was waiting for me.
And I for it.
