"Even if there were no other reasons against telling children fairy tales of sex instead of the real facts, there is one reason which ought to be decisive with every mother who values her influence over her child. He will very quickly discover, either by information from others or by his own natural intelligence, that the fairy tale that was told him in reply to a question about a simple matter of fact was a lie. With that discovery, his mother's influence over him in all such matters vanishes forever, for not only has a child a horror of being duped, but he is extremely sensitive about a rebuff of this kind, and never repeats what he has been made to feel was a mistake to be ashamed of. He will not trouble his mother with any more questions on this matter; he will not confide in her; he will himself learn the art of telling 'fairy tales' about sex matters. He had turned to his mother in trust, she had not responded with equal trust, and she must suffer the punishment, as Henriette Fürth puts it, of seeing 'the love and trust of her son stolen from her by the first boy he makes friends with in the street.'"[5] Joy is a natural consequence of a child's affection for, and faith in, his parents. Resentfulness, bitterness, sullenness, are natural consequences of loss of affection and faith. The parents of a sullen child must always ask themselves if, through deception of any sort, they have forfeited the child's esteem for them. They must further ask themselves if, by intentional or unintentional unkindness of a persistent sort, they have embittered the child. They must also put to themselves the question: "Have I in some way erred so as to make my child sullen by the force of a bad example?" And, lastly, they must not forget to probe, through the aid of a skilled physician, for possible physical causes of mental and nervous stress. If they do not adopt this course, if they allow the child to go on sulking, or if they increase his sulkiness by mishandling him, let me again warn them that they may be hopelessly limiting his chances for success and happiness in manhood. Character distortions of some sort are certain to result; even his bodily health itself may be affected. For, just as sulkiness often is a product of some physical disorder, so may it, in turn, become a _cause_ of physical disorder. To sulk is essentially to be in a disturbed emotional state, and recent scientific research has established that such states, particularly if intense or long continued, have a highly unfavourable influence on the bodily organism. This has been most clearly shown in the case of anger and worry, the former of which always is, while the latter often is, basic in sulkiness.
