问题：

One evening I went out and left my 17-year-old son and his girlfriend in charge of his 8-year-old brother and 4-year-old sister. I left with complete confidence that the older children would do a wonderful job of babysitting the younger children. Later, I discovered that I was completely wrong.

I had decided to return home earlier than planned so that my son and his girlfriend could go out. I called home with this happy news．But instead of hearing his cheerful, grateful voice on the other end of the line, all I heard was the sound of a telephone ringing.

It was, I should point out, after 10 p.m., when the two younger children should have been in bed, and when the two older children should have been answering the phone. “I’ll give him a lesson, ” I said．I decided they must be outside．Why they might be outside at 10:30 on a winter night I had no idea, but it was the only explanation I could come up with.

Finally, in desperation（绝望）, I called his girlfriend’s house. His girlfriend answered．“Yes,” she said brightly, “He’s right here.”

He came on the phone．I was not my usual calm, patient．After all, one of the rules of survival for modern parents is that you can’t trust modern teenagers. “Where are the children?” I said. He said they were with him．They had done nothing wrong．My son had taken the younger children over to his girlfriend’s house just for ice cream and cake． Well, it turns out that I shouldn’t have believed it．It was only part of the truth.

The following Saturday evening we were at my parents’ home, celebrating my birthday．My oldest son gave me the children’s gifts --- a series of lovely color photographs of my children, dressed in their best clothes, and wearing their most wonderful expressions. They are pictures to treasure a lifetime, all taken by the father of my son’s girlfriend.
