Fans of 1960s music, my 14-year-old daughter and her best friend got front-row tickets to a concert. When they returned home, my daughter said, “During the show, we looked back and saw hundreds of little lights swaying to the music. At first we thought the people were holding up cigarette lighters. Then we realized that the lights were the reflections off all the eyeglasses in the audience.”
我14歲的女兒和她最要好的朋友是20世紀60年代音樂迷。她們得到了一個音樂會的前排座位。等她們回到家里,我女兒說:“在演出期間,我們回頭看到幾百個小亮點隨著音樂搖擺。起初我們以為是人們拿著打火機。后來才意識到這些亮點是聽眾所戴眼鏡的反光。”
