Three Chinese families (including mine) resided near the university where we adults were going to graduate school. We got along well and often watched one another’s children during classes. For the summer break, we decided to go on a trip together, since few of us had had a chance to see the eastern part of the United States and Canada. Each family had one child, making nine people in all. Financially, the families could not afford to go separately, which was why we wanted to go as a group. We intended to share all the expenses—including auto rental and insurance, gasoline, the cost of the luggage rack, accommodation, and child care—and to take turns driving.
