Infancy is not what it is cracked up to be. The child seems happy all the time to the adult, because the adult knows that the child is untouched by the real problems of life; if the adult were similarly untouched he is sure that he would be happy. But children, not knowing that they are having an easy time, have a good many hard times. Growing and learning and obeying the rules of their elders, or fighting against them, are not easy things to do.
