I think we should try to find a happy memory, something to lift us on those unpleasant days．I'm saying this because I think I have just found mine．
I had some work in Glasgow then．I was on a really 31 schedule, which meant I would have no time for myself all day．I was having one of those days, when the train was completely _32 and the conversation around me seemed to be particularly 33 ．Besides, I had a bit of headache． 34_ quickly across the station hall, I fished some 35 from my pocket．There was usually someone at the exit 36 the Big Issue （a magazine that helps homeless folk earn a living）．
37 the crowd parted ways at the bottom of the hall, I saw someone selling the Big Issue．She really looked like she had been sleeping 38 ．Her clothes were 39 and she obviously hadn't had a scrub （擦洗） for quite a while．
As I 40 the exit, I saw that she was also 41 from side to side．At first I thought she was trying to keep 42 against the biting wind．But she wasn't．She was moving in time to a 43 ．I couldn't hear her, but I could see her lips moving．
When I got closer, I saw a white 44 hanging from her elbow and noticed that she had sunken eyes．She was 45 , dirty and living on the streets．I came closer and through the 46 of the traffic I could hear her 47 the immortal （不朽的） line, "．．．And I think to myself, what a wonderful world!"
I bought her last magazine for twice what I had originally 48 ．She thanked me and _49 her belongings and went tapping off along the pavement—still singing．
So, I have my happy 50 for thatday, and I think it will stay with me a long, long time.
