I teach biology at UNLV three times per week. Last Monday ,at the beginning of class, I cheerfully asked my  1   how their weekend had been. One young man said that his weekend had not been so   2  . He had his wisdom teeth removed. Then he went on to ask me why I always seemed to be so 3   .

       His question  4    me of something I’d read somewhere before: “Every morning when you get up ,you have a   5  about how you want to deal with life that day,” I said. “I choose to be cheerful.

       “Let me give you an example,” I continued,   6  all sixty students in the class. “In  7    to teaching here at UNLV, I also teach out at a  8  in Henderson, 17 miles down the highway from where I live. One day a few weeks ago I drove those 17 miles to Henderson. I   9   the highway and turned onto College Drive .I only had to drive another quarter mile down the road to the college .But just then my car  10  . I tried to start it again, but the   11  wouldn’t work. 12    I turned my flashers on, took my books, and  13  down the road to the college.

       “As soon as I got there ,I called and   14  for a tow truck to meet me at my car after  15   . The secretary there asked me what had happened. “This is my  16  day,” I replied, smiling.

       She was  17  . “What do you mean?”

       “My car could have broken down anywhere along the highway. It didn’t .” I replied. “   18 , it broke down in the perfect place: off the highway,   19  walking distance of here.

       I’m still able to teach my class , and I’ve been able to arrange for the tow truck to meet me after class. If my car was meant to break down today, it couldn’t have been arranged in a more convenient  20    .”

       I ended my story. In spite of the early hour, no one in my class seemed to be asleep. Somehow ,my story had touched them.
