“The man could talk a nun out of her habit. And a good girl into a series of bad ones.”
"Always Coming Home" – Ursula K. Le Guin (p. 316)
Shit just got real. A little further down the page, there's a passage that can be read as Le Guin breaking the fourth wall and critiquing her writing of this very text, and then the other character in the dialogue says, "You can't talk that way!" and the potential Le Guin stand-in is like, "True."
I don't think I've ever read a book quite like this.
