I teach computer courses, and my students often call me at home with questions. One morning I was on the phone, explaining in computer language the solution to a problem, while a repairman was fixing my refrigerator. After an endless stream of "C colon¹, back- slash², greater than, cd, backslash, DOS, 0 colon" and so on, I hung up and found the repairman staring at me. "Lady," he asked, are you a spy?"

我教计算机课程，我的学生经常打电话到我家问我问题。一天早晨，我在电话里用计算机语言解释一个问题的答案，当时一个维修工正在给我修电冰箱。经过一连串的“C冒号，回车，大于号，CD，回车，DOS，C冒号”等等，我挂上电话发现那位维修工在盯着我。“女士，”他问，“你是个间谍吗？”
