Valentine: …I lov’d a Woman, and lov’d her so long, that I found out a strange thing: I found out what a Woman was good for.
Tattle: Ay, prithee, what’s that?
Valentine: Why, to keep a Secret.
Tattle: O Lord!
Valentine: O exceeding good to keep a Secret: For tho’ she should tell, yet she is not to be believ’d.

William Congreve, Love for Love
