I was tired and hungry after a long day of work. When I walked into the living-room, my 12-year-old son looked 36 at me and said, “I love you.” I didn't know what to say. 37 several seconds all I could do was to stand there and 38 down at him . My first thought was that he must need 39 with his homework or he was trying to 40 me for some news. Finally I asked, “What was that all about?” “Nothing,” he said. “My teacher said we should 41 our parents that we love them and sees what they say. It’s 42 . The next day I called his teacher to find out more about this “experiment” and how the other parents had 43 . “Basically, most of the fathers had the 44 reaction as you did,” the teacher said. “When I first 45 we try this, I asked the children what they thought their parents would say. Some of them thought their parents would have heart trouble. “The 46 is,” the teacher explained, “feeling loved is an important part of 47 . It is something all people 48 . What I'm trying to tell the children is that it's too 49 we don't all express those feeling. A boy 50 tell his dad he loves him.” The teacher, a middle-aged man, understands how 51 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 for a (n) 52 moment. And just 53 he pulled away , 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 one of my children says “I love you”, it would not take me a whole 54 to think of the right 55 .
