In 1935I got engaged（订婚），but （38） 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 still very（39） ．
I came to your （40） to buy a ring．The salesgirl 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 （41） _ back，I said I did not know the size of my girl﹣friend's finger．So I left the shop （42） _ paying．
My wife died a short while ago and all these years I've been feeling（43） that I never paid for her ring．At that time the ring cost£2，so I think （44） may cost£10now，and I am sending you the money．
Yours truly，
A customer
