VIOLA: Most sweet lady –
OLIVIA: A comfortable doctrine, and much may be said of it. Where lies your text?
VIOLA: In Orsino’s bosom.
OLIVIA: In his bosom? In what chapter of his bosom?
VIOLA: To answer by the method, in the first of his heart.
OLIVIA: O, I have read it; it is heresy. Have you no more to say?

– William Shakespeare

Twelfth Night, Act 1, Scene 5. Olivia reads Orsino like a book. And suggests that his bid to woo her through his messenger Viola is a book that she has read before. She is suggesting Orsino’s words of love are not very original.
