"A child is dying---out of breath!" I had just begun my working day in the city, when those words came through the radio of the police car I was driving. I turned on the red lights and siren  and drove off as fast as I could. "Just my luck!" I thought. I did not know this city well and my first call of the day was a life-and-death sudden happening, several kilometers away.     I got to the house. A mother, filled with fear, handed me her baby, his face already blue. Was I too late? Dear me!      I did what I had been taught to do in such a serious condition. A small thing flew out of the baby's mouth onto the floor. It was a button. Thanks heavens! The holes in it let a little air through.       The doctor rushed into the room. He had with him an oxygen  bag.        The child began to cry at the top of his voice, turned red and started to look for his mother. He was angry but saved. What did the writer mean when he said to himself "Just my luck!"?
It was a good chance for him to practice what he had learned before He was happy to have such a serious matter on his working day He was not at all happy to have so serious a matter on his working day He had been long waiting for the day to come.
