The corner of the eye

Subtle emotions ; sidelong glances
The  corner of the eye, the view of you
Noone else can see.
The rolling ego,the raising of the brow
The humorous glimpse, the grasp
The  network of our eyes
We’re spies
We’re in touch already
Some poet introduces you.
A sign of being ,say,  a late reactor
But the explosion is  on the way
We don’t know ;  our eyes work
Some  are lit ; candles in a window
I think you know; stop it and start; again
