The youth who avoids the friendship of his own sex, or the one who is not attracted by the opposite sex, is abnormal, and either of these cases should be taken as a disorder and should be treated in its early stages. If it is allowed to go on it results in great disappointment. The youth who is disinclined to associate with his own sex is as a rule a timid nature and weak in will-power. It is sometimes caused by feebleness of body and sometimes by having been brought up with extra love, care, and tenderness at the hands of women alone. Therefore the life of a boy should begin with having boys as companions. In this way he receives from others the nature which is necessary for him.
