In ancient Greece there once lived a clever man. His name was Aesop.
One day, when Aesop was taking a walk in the country, a traveler stopped him and said. "Kind sir, can you tell me how soon I can get to town?"
"Go, "Aesop answered.
"I know I must go, "said the traveler. "But I want to know how soon I can get to town. "
"Go, "Aesop shouted to him.
The traveler was very angry. "This man must be mad," he thought. And he walked away.
Suddenly he heard Aesop shouting to him, "You will get to town in two hours."
The traveler was greatly surprised. He turned back and asked, "Why didn't you tell me that before?"
"How could I have told you that before?" answered Aesop. "l didn't know how fast you could walk."
