Now and again, one could detect in a childless woman of a certain age the various characteristics of all the children she had never issued. Her body was haunted by the ghost of souls who hadn't lived yet. Premature ghosts. Half-ghosts. X's without Y's. Y's without X's. They applied at her womb and were denied, but, meant for her and no one else, they wouldn't go away. Like tiny ectoplasmic gophers, they hunkered in her tear ducts. They shone through her sighs. Often to her chagrin, they would soften the voice she used in the marketplace. When she spilled wine, it was their playful antics that jostled the glass. They called out her name in the bath or when she passed real children in the street. The spirit babies were everywhere her companions, and everywhere they left her lonesome - yet they no more bore her resentment than a seed resents uneaten fruit. Like pet gnats, like phosphorescence, like sighs on a string, they would follow her into eternity.
