Mr. Grey usually went to work by subway. He liked walking from a station to his office unless it was raining, because he could take some exercises. One morning he was walking along the street while a stranger stopped him and said to him, “You may not remember me, sir, but seven years before I came to London without a penny in my pockets. I stopped you in this street and asked you lend me some money, and you give me £5. You said you were willing to take a chance to give us a new start.” Mr. Grey felt a bit of surprised and thought for a few minutes. Then he said, “Yes, I remember you. Going on with your story.” “Well,” answered the stranger, “were you still willing to take a chance?”
