The Fox and the Lion
A Fox who had never seen a lion in his life met one of the greatest size. In his terror and surprise, he thought that his last hour had come. At the second meeting, he was still somewhat alarmed, but less so than at first. At the third sight of the Lion, he felt no fear at all, but walked up to the Lion and began to converse with him.
By force of habit we become enabled to confront, unmoved, things the most terrible and dangerous.
