I can't count how many times people have said, while shaking their heads in disappointment,"I just don't know what is with teenagers today. "
    The other day I was in my car on my way to the farmers market with my friend Jerry when we passed two teens standing by the side of the road with a car wash sign.
My car was dirty with spots on, so I pulled over. There were teenagers everywhere.There was a group directing the cars and another group spraying them down. As they wiped over every square inch of my dirty car, I couldn't help but wonder why thirty teenagers had devoted such a beautiful Saturday to washing cars-what might be their motivation(动机)?
    Finally, after I handed them a twenty-dollar bill, I asked what they were raising money for. They explained to me that a friend of theirs, C.T. Schmitz, had recently been diagnosed（诊断） with cancer. He badly needed money for his illness. He had gone to school with the teenagers who were there that day and each of them thought he was sweeter than any other they had known. His friend Kevin had decided to put this car wash together. He told me that they wanted to raise some money to let C.T. know that they thought he was always among them.
    They handed me a bag of homemade cookies with my receipt and we drove away.I asked Jerry to read to me what the tag tied to the bag said. It said simply,"Thanks,
sir, for helping us to help C. T. "
    Yeah! I don't know what is with teenagers today!
