3. Observers should report with especial care all cases of unusually close relationship between children in youth, such as childish favoritism, "platonic friendships," "chumming," in school or home, etc. We have in these facts--and there is a very great variety of them--an exaggeration of the social or imitative tendency, a narrowing down of the personal sensibility to a peculiar line of well-formed influences. It has never been studied by writers either on the genesis of social emotion or on the practice of education. To be sure, teachers have been alive to the pros and cons of allowing children and students to room together; but that has been with view to the possibility of direct immoral or unwholesome contagion. This danger is certainly real; but we, as psychological observers, and above all as teachers and leaders of our children, must go deeper than that. Consider, for example, the possible influence of a school chum and roommate upon a girl in her teens; for this is only an evident case of what all isolated children are subject to. A sensitive nature, a girl whose very life is a branch of a social tree, is placed in a new environment, to engraft upon the members of her mutilated self--her very personality; it is nothing less than that--utterly new channels of supply. The only safety possible, the only way to conserve the lessons of her past, apart from the veriest chance, and to add to the structure of her present character, lies in securing for her the greatest possible variety of social influences. Instead of this, she is allowed to meet, eat, walk, talk, lie down at night, and rise in the morning, with one other person, a "copy" set before her, as immature in all likelihood as herself, or, if not so, yet a single personality, put there to wrap around her growing self the confining cords of unassimilated and foreign habit. Above all things, fathers, mothers, teachers, elders, give the children room! They need all that they can get, and their personalities will grow to fill it. Give them plenty of companions, fill their lives with variety; variety is the soul of originality, and its only source of supply. The ethical life itself, the boy's, the girl's, conscience, is born in the stress of the conflicts of suggestion, born right out of his imitative hesitations; and just this is the analogy which he must assimilate and depend upon in his own conflicts for self-control and social continence. So impressively true is this from the human point of view that, in my opinion--formed, it is true, from the very few data accessible on such points, still a positive opinion--friendships of a close exclusive kind should be discouraged or broken up, except when under the immediate eye of the wise parent or guardian; and even when allowed, these relationships should, in all cases, be used to entrain the sympathetic and moral sentiments into a wider field of social exercise.
