　　As my train was delayed for two hours, I had plenty of time to spare. After buying some magazines to read on the journey, I gave my wife a long-distance call. Then I 1 my way to the luggage office to collect my heavy suitcase. I had left it there three days before. There were only a few people 2 , and I took out my 3 to find the receipt 4 my case. The receipt seemed not where I had placed it. No matter how 5 I searched, the receipt was nowhere to be found.

　　When my 6 came, I 7 the situation sorrowfully to the assistant. The man looked at me 8 as if to say that he had 9 this kind of story many times and asked me to tell him 10 my case was like. I told him it was an old brown-looking object, not different 11 the many cases I could see in his office. The assistant then told me to 12 a list of what was 13 in the case. If they were 14 , he said, I could take the case away. I tried to remember all the things I had hurriedly put into the case and 15 them down as they came to me.

　　After I had done this, I went to 16 round the office. There were hundreds of 17 there. For one 18 moment, it came to my mind that if someone had picked the receipt he could have easily taken the case already. This had not happened fortunately, for I found the case 19 in the corner. After 20 the things inside, the assistant was satisfied that it was mine, and told me I could take the case away.
