题目内容：
Last week the manager of an old jeweler's shop received a letter marked "personal", so of course his secretary gave it to him unopened. As he was very busy, the letter lay on his desk till tea-time. Then he opened it and a ￡10 note fell out onto his desk. With the note was a short letter. This is what it said: Dear sir,
In 1935 I got engaged. But unfortunately at that time there was a lot of unemployment and I lost my job. I was six months without a job and then I got work again. But of course was very short of money. I came to your shop to buy a wedding ring. The assistant brought 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 girl-friend's finger. So I left the shop without buying a ring.
My wife died a short while ago and the fact that I never paid for her ring has been on my conscience (良心) all these years. At the time the ring cost ￡2 so I reckon (估计) that is a bout10 at today's price. And I am sending you that amount. Yourstruly, A customer
"Well, well, well," said the manager, "life is full of surprises!"
