Our daughter Kerrin, a student at Boston University, had been home for a week-end visit, and I dropped her off at the bus station just in time for her back to college. After Kerrin’s bus had gone and I was driving away, I noticed that she had left her purse on the passenger seat. Worried that she would arrive in Boston without money or keys to her room, I called my wife, Bette Jean, on the car phone, explaining why I would be late. As I was following the bus, Bette Jean phoned me back to say she had phoned the bus dispatcher（调度员）on the other line and he, in return, had phoned the bus driver on yet another phone. The driver asked me to wave out of my window to show where I was. Then he pulled over at a rest stop, and I did the same. Kerrin jumped off the bus, and I handed her the purse and went on my way. 11.
