One day, while Nasreddin Hodja was working in the field, a stranger passing by the road called him and asked him how long it would take to go to a nearby village. The teacher was ignorant. The man repeated the same question one more time and when he did not get an answer, he bent his neck and continued on his way. After going a long way, Hodja called after him and called the man to him. “Son,” he said, “you will get there in exactly three hours!” “Well,” said the man, “since you knew that. Why did you tire me out and didn't tell me beforehand?" Hodja replied, “How can I know how long it will take to get there without seeing how you walk?
