If ye should lead her into a fool’s paradise, as they say, it were a very gross kind of behaviour, as they say: for the gentlewoman is young; and, therefore, if you should deal double with her, truly it were an ill thing to be offered to any gentlewoman, and very weak dealing.
– William Shakespeare
Romeo and Juliet, Act 2, Scene 4. The Nurse warns Romeo not to make a fool of Juliet by leading her on and then leaving her. To take advantage of her youth and innocence and deceive her would be wicked, she says. The Nurse is acting like a protective mother to Juliet.
