【明報專訊】In his youth, Ludwig spent so much time at his piano (鋼琴) that he didn't go out to meet people. "You have no friends because you do not go anywhere," his music teacher said. "You should visit and meet people. Why don't you drop a note to some of your young friends and say hello?" That afternoon, Ludwig dropped a note to Buddy. "That's not what I meant!" his music teacher frowned (皺眉). The idiom drop a note means to write a letter or a message to someone."
