I was tired and hungry after a long day of work. When I walked into the living-room, my 12-year-old son looked up at me and said, “I love you.” I did not know 1 to say, and I just stood there, looking 2 at him. My first thought was that he must need 3 with his homework or he was trying to prepare me for some news. Finally I asked, “What was that all about ?” “Nothing,” he said, “My teacher said we should 4 our parents we love them and see what they say. It’s an experience( 实验 ) .” The next day I called his 5 to find more about his “experiment” and how the other parents said. “Most of the fathers said the same word as you did,” the teacher said, ”When I first 6 we try this, I asked the children what they thought their parents would say. Some of them thought their parents would 7 trouble.” The point is that feeling loved is an important part of life. It’s something all people 8 . What I’m trying to tell them it’s too bad that we don’t express those feelings. A boy should be 9 to tell his dad that he loves him.” The teacher 10 how difficult it is for some of us to say the things that would be good for us to say. When my son came to me that evening, I held on to him. I said in my deepest, most manly voice, “Hey, I love you, too.” I don’t know if saying that made either of us healthier, but it did feel pretty good. Maybe next time if my child says “I love you”, it would not take me a whole day to think of the right answer.
