‘Tis beauty truly blent, whose red and white
Nature’s own sweet and cunning hand laid on:
Lady, you are the cruell’st she alive
If you will lead these graces to the grave
And leave the world no copy.

– William Shakespeare

Twelfth Night, Act 1, Scene 5. Viola, disguised as Cesario, rebukes Olivia for rejecting Orsino’s love and insisting on staying a single woman. She tells Olivia that it would be a cruel disservice to the world for a woman so beautiful not to produce an heir. Her advice about marriage and children takes on a greater significance because Viola is speaking to Olivia as another woman.
