First, I made a stand by stacking some boxes from the storeroom. Then I covered it with a floral-print tablecloth and set out a plate. I put crackers on the plate, took my beater from the bag, and began whipping the cream.

The noise of the beater echoes through the empty store, and I always feel a little embarrassed. I concentrate on whipping the cream, ignoring the looks from the employees gathered around their registers for the morning meeting.

The store had just been renovated, so the floor was spotless and everything seemed to shine. I spooned little dabs of whipped cream onto the crackers and offered them to customers as they passed by. I always repeat the sales pitch exactly as it's printed in the manual from the agency. "Please try some. It's on sale today. What could be better with your favorite homemade cake?" I rarely say anything else.

All sorts of people passed by my stand-a lady in sandals, a young man in a sweat suit, a Filipino woman with frizzy hair. Some of them took a cracker from my plate and ate it. Some walked by with a skeptical look, and others put a carton of cream into their basket without saying anything. I gave them all the same smile. My salary has nothing to do with how many cartons I sell, so it seems easiest to be pleasant to everyone.

The first person to take a cracker today was an old woman with a bent back. She had what appeared to be a towel wrapped around her neck like a scarf, and a brown cloth purse in her hand. She was an ordinary old lady, almost invisible in the crowded supermarket.

"May I try one?" she said, coming up timidly to my table.

"Please do," I said, in my most cheerful voice.

She stared at the plate for a moment, as if she were examining some rare delicacy. Then she extended her dry, powdery fingers ever so slowly and took a cracker. The next motion, however, was amazingly quick. Her lips came open in a childish circle and she tossed the cracker into her mouth. As she bit down on it, her eyes closed appreciatively.

We stood there in the supermarket, surrounded by an infinite variety of food-behind her, stacks of meat in slices, cubes, or ground; behind me, frozen beans and piecrusts and dumplings. The tall shelves were packed tight from one wall to the other, and each shelf was overflowing with food: vegetables, dairy, sweets, spices-it seemed to go on forever. I felt dizzy just looking at it.

The shoppers passed by, baskets in hand, as if bobbing along on a stream of groceries. It occurred to me that almost everything in the store was edible, and this seemed a bit sinister. There was something disturbing about so many people converging on this one spot in search of food. And then I remembered my sister, and the way her sad eyes stared at a tiny morsel of croissant, how she seemed about to cry as she swallowed and the white crumbs scattered forlornly across the table.

As the old woman had opened her mouth to eat the cracker, I caught just a glimpse of her tongue. It was a brilliant red-in startling contrast to her pale, fragile body. Her throat was illuminated for just an instant, as the grainy surface caught the light. The whipped cream slid smoothly over her tongue and out of sight.

"Would you mind if I had another?" she said. As she bent over my plate, her purse swung back and forth in her hand. It was rare for anyone to ask for a second cracker, and I hesitated for a moment. But I caught myself almost immediately.

"Of course," I said, smiling back at her. She took another cracker in her wrinkled fingers and tossed it into her mouth, and again her crimson tongue peeked out from between her teeth. She seemed to have a healthy appetite, and there was a certain rhythm and energy to the way she ate.

"Thank you," she said, putting a container of cream in her basket.

"Thank you," I said, wondering what she would do with it when she got home. She turned, and a moment later she had disappeared into the crowd.

My sister put on a maternity dress for the first time today. Her belly suddenly seemed larger, but when she let me touch it, I could tell that it hadn't changed. I found it difficult to believe that there was a living being there under my hand. She seemed to be having a hard time getting used to the dress and kept fiddling with the ribbon around her waist.

But her morning sickness has vanished, ending just as abruptly as it began. Since the nausea started, she'd avoided the kitchen completely, so I was puzzled when I found her leaning against the counter this morning, after saying good-bye to her husband.

Because we haven't been cooking, the kitchen was spotless. Every utensil had been put away, the counter was clean and dry, and the dishwasher was empty. It seemed cold and forbidding, like a showroom. She looked around for a moment and then sat down at the table. Normally, it would have been cluttered with bottles and containers we'd forgotten to put away, but today there was nothing on it. She looked up at me as if she had something to say. The hem of her dress swirled around her ankles.

"Would you like a croissant?" I said, trying to be as discreet as possible.

"Please don't even say that horrible word," she said. I nodded obediently. "But I would like to try something else," she continued, almost whispering.

"Sure," I said. I hurried to the refrigerator, realizing that this was the first time in weeks that she'd expressed any interest in food. But there was absolutely nothing there, just a bare lightbulb illuminating the emptiness. I closed the door with a sigh and went to look in the pantry, but there was nothing there, either.

"Don't you have anything?" she said, sounding worried.

"Let's see," I said, sorting through the bags and cans and jars. "There's a little gelatin, half a sack of flour, some dried mushrooms, red food coloring, yeast, vanilla extract…" I came across two leftover croissants, but I quickly put them back.

"But I want to eat something," she said, as if making a momentous decision.

"Hold on. There must be something around here." I checked the pantry again, shelf by shelf. At the very bottom, I found some raisins we'd once bought for a cake. The date on the box said that they were more than two years old, and they were as dried out as a mummy's eyeballs. "How about these?" I asked, pushing the bag toward her. She nodded.

It was strange to watch her eat something so hard with such a satisfied expression. Her jaw worked quickly as she took handful after handful from the bag. Her whole mind and body seemed to be concentrated on eating. When she came to the last few raisins, she let them rest on her palm for a moment, studying them lovingly before slowly putting them in her mouth. That was when I understood that her morning sickness was truly gone.

In the past ten days my sister has gained back the ten pounds she lost during fourteen weeks of morning sickness. Now she seems to have something edible in her hand at every waking moment. If she's not at the table for a meal, she's clutching a bag of pastries, or looking for the can opener, or poking around in the refrigerator. It's as if her whole being had been swallowed up by her appetite.

She eats all the time, almost as a reflex, like breathing. Her eyes are clear and expressionless, fixed somewhere off in space. Her lips move vigorously, like the thighs of a sprinter. But for me very little has changed; it's just like when she was sick all the time-all I can do is sit back and watch.

She suddenly has an appetite for all sorts of strange things. One rainy night she announced that she was dying for loquat sherbet. It was raining so hard that the yard seemed to be hidden behind a curtain of white spray, and it was very late. We were all in our pajamas. It seemed unlikely that any store in the neighborhood would be open, not to mention the fact that I wasn't even sure there was such a thing as loquat sherbet.
