When my son was a hign-school sophomore, he got a part-time job sacking groceries at a supermarket. He came home all smiles."How was your first day?" I asked."It was great, Dad," he replied. "I got to talk to some good-looking girls."Since Stephen is not very talkative, I asked, "What did you say to them?""Do you prefer paper or plastic?"我儿子在一所中学读二年级时，在一家超级市场找到了一份包装商品的业余工作。他满面笑容地回到了家。“第一天感觉如何？”我问。“好极了，爸爸。”他答道，“我跟许多漂亮的女孩子讲了话。”由于斯蒂芬不善言谈，我问道：“你跟他们说了些什么？”“你是喜欢纸包装还是塑料包装？”
