【专家解说】： Last week the manager of an old shop received a letter. As he was very busy, the letter lay on his desk till teatime. Then he opened it and £10 fell out onto his desk. Together with it was a short letter. It read: Dear Sir, In 1935, I got engaged (订婚) ,but unluckily I lost my job. At that time a lot of people were out of work. Six months later, I got a job again, but of course I was very short of money.     I came to your shop to buy a wedding ring. The girl took out some rings for me to look at, but she was called away for a moment, and I put one of the rings in my pocket. When she came back, I said I did not know the size of my girlfriend’s finger. So I left the shop without paying.     My wife died a short while ago and I never paid for her ring. It has been on my conscience (良心) all these years. At that time the ring cost £2, so I think the ring may cost £10 now, and I am sending you the money.            Yours truly,              A customer
