I was tired and hungry after a long day of work.

When I walked into the living-room, my 12-year-old son 1up at me and said "I love you." I didn't know what to say. For several 2all I could do was to3 there and look at him. My first thought was that he must need 4 with his homework or he was trying to 5 me for some news.

Finally, I asked, "What was that all about?"

"Nothing," He said, "My teacher said we should tell our parents that we love them and sees what they say. It's 6. "

The next day I called his teacher to find out more about this "experiment" and how the other parents had7.

" Most of the fathers had the 8 reacting（反应） as you did. "The teacher said, "When I first9we try this, I asked the children what they thought their parents would say. Some of them thought their parents would have heart trouble. "The10is," the teacher explained, "feeling loved is an important part of 11 . It's something all people require. What I'm trying to tell the children is that it's too 12 we don't all express those feeling. A boy should be13to tell his dad he loves him. "

The teacher, a middle-aged man, understands how14it 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（抱着） him for a more second. And just before he 15 away, I said in my deepest, most manly （有男子气概的）voice , "Hey, I love you, too. "

I don't know if saying that made either of us healthier, but it did feel pretty good.
