The Peacock is very vain, and proud of its fine feathers. I suppose that little girl is proud of her finery, and the little boy tells her she is like the Peacock. In the book of Job, we are reminded that it was God who gave the Peacock its beautiful feathers, Children should remember that they have nothing of their own to be proud of, that every thing they possess is given them by God, and they should be thankful to him for all his mercies.
