Name change

Paul saw someone in the street he recognized as his friend Woodall.

“Woodall,” he said, “what happened to you? You used to be fat and now you’re thin. You used to have hair and now you’re bald. You used to have perfect eyesight and now you wear glasses.”

The man looked at him in astonishment.

“Listen, sir, my name is not Woodall. It’s Wain.”

“Oh!” Paul exclaimed. “You’ve changed your name too!”
