A very old lady won a million dollars in a lottery( * * ). Her son and her husband heard the news on the radio.

“How are we going to tell your mother?” the man asked. “The news might kill her!”

“That’s true,” the son said. “Perhaps we’d better speak to her doctor about it. He’ll know how to bring her the news gently.”

They told the old lady’s doctor about this.

“I’m glad you told me, ” he said “A shock(震惊), even a happy one, could give her a heart attack, leave it to me. I’ll find a way of bringing the news to her.”

The doctor thought about the problem for several days, then decided what he would say.

He called on the old lady and sat by her. He took her hand in his.

“Let’s play a game, my dear,” he said. “‘Let’s pretend(假装)’ game.”

“Oh, yes, ” the old lady said. “I love ‘Let’s pretend’ game.”

“Good, I’ll ask you a question first, ” the doctor said, “Then you can ask me one.”

He pretended to think for a few minutes. Then he said, “Tell me, what would you do if you won a million dollars in the lottery?”

“Oh, that’s an easy one,” the old lady said, “I’d give most of it to you, doctor, because you have been so good to me all these years, doctor!” But the doctor was now lying on the floor. He had died of shock.
