There Taotao would be left in the hands of the American flight attendants. Barely six, he wasn't allowed to change planes unaccompanied, so his parents would have to go and collect him in San Francisco. The travel agent, a bosomy brunette with olive skin and long hair, helped Nan make a reservation for the least expensive room at a hotel near Union Square, where the three of them would stay the first night before flying back to Boston. Altogether the trip would cost them close to $3,000. Never had they spent money so lavishly.

They arrived in San Francisco in the early morning of July 11. They hadn't expected it to be so chilly; nippy gusts were ruffling pedestrians' hair and forcing people to squint. A storm had descended the night before, leaving shop signs tattered and soggy; a few traffic lights were out of order, blinking endlessly. But the ebony facades of some buildings had been washed clean and glossy, and the vigorous wind smelled of the ocean. Pingping, without any warm clothes on, couldn't stop shivering and then began hiccupping violently on their way to the hotel. Nan tried massaging the nape of her neck to relieve her spasms, and once or twice he slapped her back in an attempt to shock her out of them. This trick had worked before, but it didn't help today.

Nan had called United Airlines twice to find out whether Taotao was actually on the plane, but nothing could be confirmed. He was told that the boy's name didn't come up in the computer. Things were still chaotic in China, and many passengers had been switched to this flight from other airlines that had canceled their services, so there wasn't a complete passenger list yet. "Don't worry, Mr. Wu," a pleasant female voice consoled Nan. "Your son should be all right."

"We were told zat he is on zer plane." Nan often mismanaged the interdental sound that the Chinese language doesn't have.

"Then he should be."

"Do you have anozzer way to check zat?"
