The dark crescent under our eyes

I wonder what my mother felt at night,
As something burrowed in my skull and sat itself heavy
till blood turned bone,
And my eyes took rest
In the place where the burrowing thing died.

I didn’t know that I’d look like so many people I feel but have never seen before. When I see the dark under my eyes and the new dark on my lips, I sense a woman I have always known but am yet to meet.
