     Once* there was a man whose wife was dumb. But he loved her very much and went to the
doctor. “Can you make my wife speak?” he asked. “Yes, I can. You may come for the operation
tomorrow”, said the doctor. The operation had been done and the woman could speak. But she
spoke so much that the man had to run back to the doctor. “You ought to make my wife dumb
again”, he said. But the doctor answered that nobody could make the woman stop talking. The
man cried: “What must I do? I shall die* if I have to listen to her all day”. The doctor answered:
“I can’t make her dumb, but I am able to make you deaf* ”. The man was thinking the matter
