There once was a man and a woman who had been married for more than 60 years. They talked about everything. They kept no secrets from each other…except that the old woman had a shoe box in the top of her closet and she told her husband never to open it or ask her about it.
For an these years the husband had never thought about the box, but one day the little old woman got very sick and the doctor said she would never recover.
In trying to sort out things they had, the little old man took down the shoe box from the top of the closet and took it to his wife's bedside. She agreed it was time that he should know what was in the box.
When he opened it, he found two beautifully crocheted (钩针编织的) doilies (装饰垫) and some money. He counted the money. It was $25,000 in total. He asked his wife about the unusual contents.
"When we were married," she said, "my grandmother told me the secret of a happy marriage was to never argue. She told me that if I ever got angry with you, I should just keep quiet and crochet a doily."
The little old man was so moved, and he had to fight back tears. Only two precious doilies were in the box. She had only been angry with him two times in all those years of living and loving. He was filled with joy and happiness.
"Sweetheart," he said, "that explains the doilies, but what about all this money? Where did it all come from?"
"Oh," she said, "that's the money I made from selling the doilies."
