Shelly Cai was 18 years old when she left the southern Chinese metropolis of Nanjing to enroll in the University of Wisconsin-Madison. In August 2010, after a 13-hour flight from Shanghai to Chicago and a three-hour bus ride, Cai finally arrived in Madison, where a distant cousin picked her up. During orientation, Cai found herself jet lagged, struggling to make sense of all the English. Five days in, she learned her grandfather in Nanjing had passed away.
