Poem of Undoing- by Sharon Venezio

How many kinds of undoing are there?
The word love in the back of my throat,
mouth ajar, as I don't say your name.

Is unhappiness a kind of undoing?
The heart's fault line, a fracture
in the space between two bodies.

My heart is a thirsty artichoke,
each petal a different version of undoing.

If I knock three times, will you reappear?
