"Who is it?" I say to the woman next to me; into her ear, or where her ear must be under the white headdress. I almost have to shout, the noise is so loud.

"Ofwarren," she shouts back. Impulsively, she grabs my hand, squeezes it as we lurch around the corner; she turns to me and I see her face, there are tears running down her cheeks, but tears of what? Envy, disappointment? But no, she's laughing, she throws her arms around me, I've never seen her before, she hugs me, she has large breasts, under the red habit, she wipes her sleeve across her face. On this day we can do anything we want.

I revise that: within limits.

Across from us on the other bench, one woman is praying, eyes closed, hands up to her mouth. Or she may not be praying. She may be biting her thumbnails. Possibly she's trying to keep calm. The third woman is calm already, she sits with her arms folded, smiling a little. The siren goes on and on. That used to be the sound of death, for ambulances or fires. Possibly it will be the sound of death today also. We will soon know. What will Ofwarren give birth to? A baby, as we all hope? Or something else, an Unbaby, with a pinhead or a snout like a dog's, or two bodies, or a hole in its heart or no arms, or webbed hands and feet? There's no telling. They could tell once, with machines, but that is now outlawed. What would be the point of knowing, anyway? You can't have them taken out; whatever it is must be carried to term.

The chances are one in four, we learned that at the Center. The air got too full, once, of chemicals, rays, radiation, the water swarmed with toxic molecules, all of that takes years to clean up, and meanwhile they creep into your body, camp out in your fatty cells. Who knows, your very flesh may be polluted, dirty as an oily beach, sure death to shore birds and unborn babies. Maybe a vulture would die of eating you. Maybe you light up in the dark, like an old-fashioned watch. Deathwatch. That's a kind of beetle, it buries carrion.

I can't think of myself, my body, sometimes, without seeing the skeleton: how I must appear to an electron. A cradle of life, made of bones; and within, hazards, warped proteins, bad crystals jagged as glass. Women took medicines, pills, men sprayed trees, cows ate grass, all that souped-up piss flowed into the rivers. Not to mention the exploding atomic power plants, along the San Andreas fault, nobody's fault, during the earthquakes, and the mutant strain of syphilis no mold could touch. Some did it themselves, had themselves tied shut with catgut or scarred with chemicals. How could they, said Aunt Lydia, oh how could they have done such a thing? Jezebels! Scorning God's gifts! Wringing her hands.

It's a risk you're taking, said Aunt Lydia, but you are the shock troops, you will march out in advance, into dangerous territory. The greater the risk the greater the glory. She clasped her hands, radiant with our phony courage. We looked down at the tops of our desks. To go through all that and give birth to a shredder: it wasn't a fine thought. We didn't know exactly what would happen to the babies that didn't get passed, that were declared Unbabies. But we knew they were put somewhere, quickly, away.
