某人有两个孩子，一个儿子和一个女儿。儿子长相英俊，而女儿却相貌平平。有一天，兄妹俩在妈妈的房间里玩，偶然走到镜子前，第一次看见了自己的真实面目。哥哥看到自己是个英俊的小伙子，就开始向妹妹鼓吹自己的相貌；从妹妹的角度来说，她一看到自己相貌平平，都快要哭出来了，就把哥哥的自夸当成了对自己的嘲笑。她便跑到父亲跟前，抱怨说哥哥太自负了，而且还乱动妈妈的东西。父亲笑着亲吻了两个孩子，并说：“我的好孩子，今后你们可要好好利用这个镜子。我的儿子，你可要像自己的英俊相貌一样努力出众；我的女儿，可以用你的美德来弥补相貌上的不足。”

BROTHER AND SISTER
A certain man had two children，a boy and a girl：and the boy was as good—looking as the girl was plain.One day,as they were playing together in their mother’S chamber，they chanced upon a mirror and saw their own features for the first time.The boy saw what a handsome fellow he was，and began to boast to his Sister about his good looks she，on her part，was ready to cry with vexation when she was aware of her plainness，and took his remarks as an insult to herself.Running to her father,she told him of her Brother’S conceit，and accused him of meddling with his mother’S things.He laughed and kissed them both，and said，“My children，learn from now onwards to make a good use ofthe glass.You，my boy，strive to be as good as it shows you to be handsome；and you，my girl，resolve to make up for the plainness of your features by the sweetness ofyour disposition.”
