I think we should try to find a happy memory, something to lift us up on those unpleasant days. I`m saying this because I think I just found mine! I had some work in Glasgow then. I was on a really 1 schedule, which meant I would have no time for myself all day. I was having one of those days, when the train was completely 2 and the conversation going on around me seemed to be particularly 3 . Besides, I had a bit of a headache. 4 quickly across the station hall, I fished some 5 from my pocket. There was usually someone at the exit 6 the Big Issue (a magazine that helps homeless folk earn a living). 7 the crowd parted ways at the bottom of the hall, I saw someone selling the Big Issue. She really looked like she`d been sleeping 8 . Her clothes were 9 and she obviously hadn`t had a scrub up (擦洗) for quite a while. As I 10 the exit, I saw that she was 11 from side to side. At first I thought she was trying to keep 12 against the biting wind. But she wasn`t. She was moving in time to a 13 . I couldn't hear her, but I could see her lips moving. When I got closer, I saw a white 14 hanging from her elbow and noticed that she had sunken eyes. She was 15 , dirty and living on streets. I came closer and through the 16 of the traffic I could hear her 17 the immortal (不朽的) line,"…And I think to myself, what a wonderful world!". I bought her last magazine for twice what I'd originally 18 . She thanked me, and 19 her belongings and went tapping off along the pavement -still singing! So, I have my happy 20 for the day, and I think it will stay with me a long,long time. | ||||
