I met Dr. Nikaido once, when he brought her home during a typhoon. He's a middle-aged man with an unremarkable face, and he made no impression on me at all. In fact, afterward I couldn't recall a single feature- thick earlobes, for example, or strong fingers-nothing. He just stood quietly behind my sister, looking down at the ground. Perhaps because his shoulders and hair were wet from the rain, he seemed terribly sad. I don't really know what kind of therapy he practices, but my sister has mentioned psychological tests and medication of some sort. In any case, she's been going to him since she was in high school, more than ten years now without a break, but I can't see that she's got any better. Her emotional problems seem to come in waves, like seaweed tossed around in the ocean, and she's never found a safe, calm shore to rest on. Still, she told me she feels much better when she's at his office.

"It's like when they're shampooing your hair at the salon," she said. "The feeling that someone's taking care of you-it's wonderful." Her eyes narrowed with pleasure at the thought of him.

But it's hard for me to believe that Dr. Nikaido is a good psychiatrist. As he stood mutely in the doorway on the night of the typhoon, he looked more like a frightened patient than a doctor.

The sun had set and a golden moon had risen in the darkness, but she still hadn't come home. "She shouldn't be out in this cold," my brother-in-law muttered. When a taxi finally stopped at the gate, he hurried out to meet her. Her eyes glistened as she unwound her scarf, and she seemed much calmer than she was this morning. But no matter how often she goes to see Dr. Nikaido, her morning sickness is as bad as ever.

It suddenly occurred to me that I haven't been thinking about the baby. I suppose I should be wondering whether it's a boy or a girl, what they'll name it, what sorts of baby clothes to buy. I imagine people usually enjoy thinking about those kinds of things. But my sister and her husband never talk about the baby in front of me. They act as if there's no connection between the pregnancy and the fact that there's a baby in her belly. Which may explain why it has no concrete existence for me.

At the moment, I use the word "chromosome" to help me remember that there's actually a baby in there. "Chromosome" helps me give it some kind of form. I once saw a picture of chromosomes in a science magazine. They looked like pairs of butterfly cocoons lined up in a row. They were oblong, and just the right size and shape to pinch in your fingers. The pairs were all different: some were curved at the ends like a cane, others were perfectly straight and parallel, and others were backed up against each other like Siamese twins. When I think about my sister's baby, I count off these twin cocoons in my head.

She hardly looks pregnant at all, even though she's entering her fifth month. For weeks now, she's consumed nothing but croissants and sports drinks, and she's losing a lot of weight. Except for her visits to the clinic and to Dr. Nikaido, she stays in bed all day, as if she were seriously ill.

About the only thing I can do for her is to avoid creating any kind of odor, so I've changed every bar of soap in the house to an unscented brand, and I took the paprika and thyme and sage from the spice rack and put them in a tin. I moved all the makeup that was in her room to mine, and, since she'd started complaining about the smell of the toothpaste, my brother-in-law went out and bought a Water Pik. Needless to say, I try not to cook when she's around. But, if I absolutely have to make something, I take the rice cooker or the microwave or the coffee grinder out to the garden and spread a mat on the ground.

It's peaceful eating outside by myself, looking up at the night sky. The evenings are warmer now that spring is almost here, and the air feels soft. My hands and feet pressed against the mat are dull and numb, but everything else-the crepe myrtle, the bricks lining the flower beds, the twinkling stars-is sharp and clear. Except for a dog barking in the distance, the evening is perfectly still.

I plug the rice cooker into the extension cord I've strung out from the kitchen, and within a few minutes a cloud of steam rises from the vent and vanishes into the darkness. A packet of instant stew warms in the microwave. From time to time, a light breeze blows, rustling the leaves and carrying away the vapor.

I eat more slowly when I'm in the garden. The cups and dishes set out on the mat are all at slightly different angles. As I serve myself the stew, being careful not to spill it, I feel as though I were playing house. A faint light is burning in my sister's window on the second floor. I think about her, curled up in bed, surrounded by all those odors, and then I open my mouth wide to take in the darkness with my bite of stew.

My brother-in-law's parents came to visit, and they brought along an odd-looking package wrapped in a scarf. Even after his mother unwrapped it, I had no idea what it was. It was just a long strip of white cloth about a foot wide. My brother-in-law unfolded it, and then we could see that it had a design of a dog printed at the edge. The dog's ears were standing up, and it looked alert and lively.

"Today is the Dog Day of the fifth month," said my sister. Her voice was weak and she couldn't hide her nausea, even in front of her husband's parents.

"I hope you don't mind, but these are supposed to bring good luck." As she spoke, her mother-in-law brought out a piece of bamboo, a ball of red cord, and a little silver bell, and lined them up in front of us. Finally, she produced a pamphlet from a shrine explaining how to use all these things to make a charm for a safe delivery.

"It even comes with instructions," I said, duly impressed.

"They sell it as a set at the shrine," she said, smiling cheerfully. As I watched my sister's slender fingers play over the pamphlet, I wondered whether the dye in the material or the mysterious piece of bamboo would give off odors. We passed the charms around, nodding solemnly and turning them over in our hands.

As soon as they were gone, my sister retreated to her room, forgetting about the gifts from the shrine. My brother-in-law wrapped them in the scarf, just as they'd come. The bell made a faint tinkling sound.

"Why is there a dog on the cloth?" I asked him.

"Dogs have lots of puppies without too much trouble. So they use them on these charms."

"Do animals know the difference between an easy birth and a hard one?"

"I imagine they do."

"Do you suppose puppies pop out like peas popping out of the pod?"

"You've got me." The dog on the scarf seemed to be watching us.

I got up early today, since the supermarket I had to go to for my part-time job was quite far away. It was foggy, and my eyelashes were cold and damp by the time I reached the station.

The job suits me because my boss always sends me to a different supermarket in an unfamiliar part of town, and I never go to the same place twice. The supermarket is usually situated on a little plaza in front of a train station, with a pedestrian crossing, bicycle racks, and a bus terminal nearby. As I watch people come into the store, it makes me feel as though I'd gone away somewhere on a trip.

At the service entrance, I flash my ID card from the employment agency and the guard nods gruffly. It's depressing in the back, with boxes and wet sheets of plastic and bits of vegetable littering the floor. The fluorescent lights are dim. I wander through the store with the bag that holds my equipment, looking for the best place to set up. Today, I chose a spot between the meat counter and the frozen-food cases.
