A Roman Singer by F. Marion Crawford

In a sunny room overlooking the great courtyard of the Palazzo Carmandola, Nino sat down to give Hedwig von Lira her first lesson in Italian literature. He had not the remotest idea what the lesson would be like, for in spite of the tolerably wide acquaintance with the subject which he owed to my care and my efforts to make a scholar of him, he knew nothing about teaching. Nevertheless, as his pupil spoke the language fluently, though with the occasional use of words of low origin, like all foreigners who have grown up in Rome and have learned to speak from their servants, he anticipated little difficulty. He felt quite sure of being able to interpret the hard places, and he had learned from me to know the best and finest passages in a number of authors.

But imagine the feelings of a boy of twenty, perfectly in love, without having the smallest right to be, suddenly placed by the side of the object of his adoration, and told to teach her all he knows -- with her father in the next room and the door open between! I have always thought it was a proof of Nino's determined character, that he should have got over this first lesson without accident.
