It is painful to see how much corruption and evil there is in a young child's heart, and how soon it begins to bear fruit. Violent tempers, self-will, pride, envy, sullenness, passion, idleness, selfishness, deceit, cunning, falsehood, hypocrisy, a terrible aptness to learn what is bad, a painful slowness to learn what is good, a readiness to pretend anything in order to gain their own ends, all these things, or some of them, you must be prepared to see, even in your own flesh and blood.
