"I'm sure I don't."
"But why did you stop?"
"Because you called to me to stop."
"I did?"
"Yes, and so I stopped."
"You are mistaken, I didn't call you."
"Yes, you did, monsieur."
"But I tell you I didn't. So go on, and try to make up for the time you have lost."
"You needn't worry about that. I'll drive like mad now. I don't mean there shall be a piece of the carriage left when we get to the next station."
