“Who knows?” said Abby. She was starting to feel a little tight-lipped with her mother, crammed into this space together like astronauts. She was starting to have a highly inflamed sense of event: a single word rang and vibrated. The slightest movement could annoy, the breath, the odor. Unlike her sister, Theda, who had always remained sunny and cheerfully intimate with everyone, Abby had always been darker and left to her own devices; she and her mother had never been very close. When Abby was a child, her mother had always repelled her a bit—the oily smell of her hair, her belly button like a worm curled in a pit, the sanitary napkins in the bathroom wastebasket, horrid as a war, then later strewn along the curb by raccoons who would tear them from the trash cans at night. Once at a restaurant, when she was little, Abby had burst into an unlatched ladies’ room stall, only to find her mother sitting there in a dazed and unseemly way, peering out at her from the toilet seat like a cuckoo in a clock.
