I buried my father in my heart. Now he grows in me, my strange son, my little root who won’t drink milk, little pale foot sunk in unheard-of night, little clock spring newly wet in the fire, little grape, parent to the future wine, a son the fruit of his own son, little father I ransom with my life.
