Anthony Adverse by Hervey Allen

Anthony had made up his mind he was in love with little Angela. It was high time, he thought, that he should have a girl. It was not very difficult to persuade yourself that you were in love with Angela, who, heaven knows, was good-looking enough. Anyway, he did not as yet really know any other girl sufficiently well even to pretend to himself that he could be in love with her. "Angela Maea" he still called Angela. It was close enough to Angela mia to pass muster when whispering to her without causing him to explain how much deeper than that the name really went.

It was not quite so easy, however, to make Angela understand that you were in love with her; in love, that is, in a really formal way, a situation to be publicly, although very quietly, made apparent to everybody. Angela merely preferred to like you, to be fond of you, and not to be formal about it. In other words, you had such a good time with her, you enjoyed being with her so much, it was difficult to remember to stop to make love to her in the proper way by talking about it as Emile did to Sophie; by letting your soul "expand" as Toussaint had explained.
