Once upon a time a man whose ax was missing suspected his neighbor's son. The boy walked like a thief, looked like a thief and spoke like a thief. But the man found his ax while digging in the valley, and the next time he saw his neighbor's son, the boy walked, looked and spoke like any other child.
