A traveler came to a river one day. He hired boatman to take him to the other side. It was a windy day and the waves were very high. So the traveler was a little afraid.

　　"Are you sure we can cross the river safely?" he asked.

　　"Of course," answered the boatman. The boat left the bank.

　　"Has anyone ever been lost here before?" the anxious traveler asked again.

　　"Never," the boatman answered calmly. "My brother was drowned here last week, but we found him the next day."
