chicken and egg - here's two

It’s in my eye but not all the way in.
In among my lashes, it is touching some nerves.
My pulse, accordingly, accelerates.
Eye lid flutter, turn to shelter from the wind.
But - don’t touch -
Not big, not a lash, not a bug, just some ash, soon gone.
All it amounts to is a second of anxiety.
The danger of pain feels so real the
way it stops a moment
in another moment.
