“Next day when I went to the school the boy was not there; he was ill. Another boy reported he was kept at home on account of scarlet fever. My anxiety about him was boundless. I could think of nothing but that boy. A schoolmate had to bring me daily reports about his condition. Often I wandered in the neighborhood of his home, up and down the streets, and at night I watched the lamplit window of the room where a sister was taking care of him. Finally I heard that he was convalescing, that all danger was over, and that he would return to school in a few weeks. I had to keep a strong grip on myself at school to be able to carry on my lectures at all. My thoughts were perpetually centered on my beloved boy pupil. Continually I kept thinking: How many days longer must I keep longing? In three weeks he will be here! My heart danced with joy at the thought.... “There had to be a change. I could not keep on living that way. I took my father into confidence and he sent me to you, thinking that you would be able to furnish good advice and aid in this difficult case.” I offered at first no advice and no help. To begin with, I allowed the love-sick fellow to speak out everything that was on his mind and that in itself lightened his burden. Then I undertook to obtain an insight into his mental life before the advent of his boy love. It turned out that he had really loved and still loves but one person in the wide world: his sister. The affection for the bride was but a substitute for his love of the sister. His bride was also homosexual and loved in him but the brother of her best girl friend. As the girl friend (his sister) cooled off during their engagement, preferring another friendship (obviously led thereto by unconscious jealousy of the brother), her own affection for the young man cooled off and she promptly made use of the opportunity to break off with him. The opportunity arose conveniently enough and the severing of the engagement reacted most painfully upon the school teacher who had reasons of his own for reproaching himself most bitterly. _The more his bride kept away from his sister the greater was his indifference to the bride. But the boy resembled his sister very closely._ He never thought of this similarity before. They had the same eyes, the same color of hair, and the same voice, and these played a strong rôle with him. During that critical period his sister was interested in a certain physician. He felt he was about to lose her affection and sought a substitute for her and that he found in his pupil.... Now he was in a position to come to an understanding with his sister. She had the requisite psychologic insight to understand him fully and to lend him intelligent assistance towards his recovery.
