the backside of NOTHING

An exercise at Zelda's. We had quotes to work from. Mine was "the backside of NOTHING" which I felt was kind of difficult to work with.

the backside of NOTHING

Holding nothing high, I'll slap its backside.
Startled, it will gasp air for the first time and scream
Exactly as loud as the cold outside, as loud as a
Thousand people watching the blank night sky for lights,
As loud as my eyes, as I lie here, watching your face
For signs, in this breathless space where we move in time.
