Mrs. Brown's mother got ill in bed two days before, so she had to go and look after her.
Before she left, she spoke to her husband Mr.Brown,
“I must tell you how to do housework, but my train is leaving in half an hour’s time. I must go now.”
“Don't worry,” Mr. Brown said. “I can take care of myself.”
In fact, he could do things well without his wife. He thought, when my wife comes back tomorrow, she won’t have to wash any plates. She must be happy.
The next day, Mrs. Brown came back. When she saw the plates, she was very happy.
“How clean they are,” she said to her husband. “You do very well.”
“Yes, of course,” said Mr. Brown.“I had my meals in the restaurant.”
