They were all fourteen or fifteen in identical plaid skirts and navy blue blazers, white blouses with soft collars.

Kathleen Cornelius, her large face drawn, her lips parted, noticed that the blackboard glimpsed through her lashes bled a little at the edges but snapped to again when she opened her eyes wide. She tried this a number of times until her attention was diverted by the floating dust motes that appeared in the gloom of her lowered lashes. They were perfectly round, transparent, either dust motes or sloughed skin cells, bits of dandruff, perhaps, or perhaps merely an optical illusion, her own blood moving behind her cornea, illuminating the defects, snags, infinitesimal genetic mutations in the sticky fabric of her eye.

The interval of idleness grew longer. Was it possible there would be no class today?

Clare Keane dreamed she was still at the breakfast table. Her father was watching the coffee percolate on the stove. Annie (who in the dream was not really Annie) was stirring her cereal. Pauline was spreading soft butter on a pinch of sweet roll, covering her fingertips with it. Much to Clare’s surprise, Annie picked up her cigarette lighter which she had unaccountably left beside her plate and struck the flint three times.

“Good morning, all,” Sister Lucy said. She stood at the door, her index finger held under the three light switches as if (Clare thought) she was hoping to keep three little noses from sneezing. “In the name of the Father,” Sister began, as she walked in, not blessing herself because she held her crutch in one hand and her large leather briefcase in the other, “and of the Son.”

Overhead, the trio of fluorescent lights merely buzzed, then clicked, then flashed angrily, before coming to full, obedient light as Sister Lucy limped into the room. One by one, the girls raised their heads, touched a pencil, stored some books beneath their desks, praying with her all the while. Clare Keane had a red spot on her forehead, marking the place where her face had heavily met her forearm. Kathleen Cornelius closed her mouth.

Now the long windows pressed back the dreary day, reflected rather than filtered-showing them now, as they glanced toward it, their own white faces, dimly described-foreheads and cheeks, some chins, only blond hair, nobody’s eyes.

Sister Lucy’s desk at the front of the room now seemed as yellow as an egg yolk. She leaned against it and pulled the cuff of her metal crutch off her wrist. She rested the crutch beside her and then turned back with one uneven step to lift herself, her small and slightly twisted torso in its black dress, up onto the desk. She rearranged her body, palms pressed to the desktop, lifting her thighs once, twice, getting comfortable. Her legs in their black shoes and black opaque stockings swung girlishly.

This was not remarkable to them. They had seen her do this many times before.

She placed her folded hands in her black lap. Sister Lucy had a round face, dark though graying hair drawn back into the white band of her headpiece, large, deep-set eyes, and a small nose. Her full cheeks were pocked delicately with scars, as if marred by rain.

“Today,” she said, softly, beginning. And then paused. She had a slight overbite, a delicate fuzz above her lip, small and perfect teeth. She was known never to raise her voice, although what she did instead, for discipline’s sake, was described by the girls as “the hairy eyeball.” But there was none of that in her look now as she waited for their attention.

“Today,” she said again, her feet no longer swinging but hooked together and drawn back a bit, beneath her desk. “Today, girls, marks a terrible anniversary. The anniversary of the decision that allows women in this country to kill their own children.”

In the stillness that followed, the girls moved their eyes toward each other. Barb lowered her head and murmured, “Don’t tell my mother,” into the soft collar of her shirt, which caused one or two of the girls around her to lower their heads as well.

The sound of the rain only made the silence in the classroom seem more deliberate and profound as Sister Lucy waited, once again, for their full attention.

“I was three years old when I came down with polio,” she said. It might have been another topic altogether. “My father left us as soon as I got sick, even though my mother was expecting. Her fifth. He moved in with a woman he’d been visiting since before my older brother was born. My father was a welder,” she said, as if that explained something. “Subways and bridges. Dangerous work, but he was very good at it.” She shrugged, looked briefly at her hands, which she half opened, as if offering herself something from her own palms. “He had needs my mother couldn’t meet,” she said before she looked up again. “That’s all we were told about it. And the fact that if he had gotten polio, too, we would have been destitute. But he took care of us. He sent money, he visited. He still took my brothers to ball games. He just never lived with us again.”

She closed her hands. They were pale white against the black lap. The girls had their eyes on her now. Barb Luce wrote something in her notebook and moved the book to the edge of her desk so Clare Keane could see. It said, “As the World Turns.”

“My mother was given a series of exercises to do with me. They involved lifting and bending my legs. They were painful. I don’t remember that they were painful to me but I’m sure they were painful for her. She would sometimes strap me down on the dining-room table. Or have my brothers hold on to me. My brothers have told me how I would scream. And how my mother would cry, just tears running down her face as she was lifting my legs and bending them, and pressing them down again, the way the doctors had told her. All the while she was expecting.”

Sister Lucy’s little chin moved up and down, the way it did when she wanted to be reasonable, consider all sides. “Of course, we weren’t alone in the world,” she said. “I had an aunt and an uncle and a wonderful grandfather. We had some very nice neighbors.

And people from church helped out. It was really only later, as an adult, that I realized how hard it must have been. For my mother.”

She straightened her spine, pulling her hands closer to her waist, as if she felt a chill. “In the first place, I think she must have been humiliated,” she went on. “Four, five children in a row and she hadn’t met his needs.” She smiled a little, only one corner of her small mouth. It was clear she did not expect them to get her full meaning. “And I know she worried. Every mother worries, but what worries my mother must have had, in those days. I don’t know when she slept. I remember seeing her, long into the night, sitting up at our bedroom window with her rosary.” Sister Lucy stopped again, peering down at them all from under her thick eyelids. The sound of the rain had mixed itself with her tale so that the girls were imagining polio, pregnancy, bridges and subways and long nights at bedroom windows as all a part of the same dark weather.

She smiled once more. Her lips were pink and smooth. “But my mother took me to the clinic and she took me home and she did the exercises the doctors told her to do. And she fixed our meals and washed our clothes and kept the apartment clean. All the while she was getting bigger and bigger with the new baby. All the while she slept alone and woke alone and sat alone through the night after she’d put out our lights.”

One of the girls made a sympathetic sound and Sister Lucy’s eyes briefly fell on her. “Girls,” she said, as if to correct something. “In an abortion, a child is pulled from a mother’s womb. If the child is very new, an embryo, it is a simple enough thing to do. There is more blood than flesh. If the child has grown any, arms and legs must sometimes be broken, or a skull must be cracked. There are some procedures, I am told, in which the mother’s womb is filled with saline, salt water, the baby essentially drowned like a kitten and then flushed from the mother’s body.” She paused only briefly.
