Joan was nothing more than a friend. He was not in love with her. One does not fall in love with a girl whom one has met only three times. One is attracted, yes; but one does not fall in love. A moment's reflection enabled him to diagnose his sensations correctly. This odd impulse to leap across the compartment and kiss Joan was not love. It was merely the natural desire of a good-hearted young man to be decently chummy with his species.
