The one next to me, with the iron glasses, said she taught English and her friend taught history and American government. Then I started wondering like a bastard what the one sitting next to me, that taught English, thought about, being a nun and all, when she read certain books for English. Books not necessarily with a lot of sexy stuff in them, but books with lovers and all in them. Take old Eustacia Vye, in The Return of the Native by Thomas Hardy. She wasn’t too sexy or anything, but even so you can’t help wondering what a nun maybe thinks about when she reads about old Eustacia. I didn’t say anything, though, naturally. All I said was English was my best subject.

The Catcher in the Rye. Chapter 15, Holden is sitting beside two nuns and wonders what nuns think when they are reading books with lovers in them. But he is too polite to say this and, despite his negativity towards religion, shows reverence to the two nuns.
