HARRIET: Are you happy?
SERENA: What an extraordinary question! Why shouldn’t I be?
HARRIET: I have no way of knowing. I merely asked if you were.
SERENA: You are quite irrepressible, Harriet.
HARRIET: Is it offensive to question the happiness of those one is fond of?
SERENA: No, not offensive. Just a little startling perhaps.
HARRIET: Why startling?
SERENA: Because it gives a jolt to complacency, I suppose. A sudden query flung at random can pierce habitual armor.
—Noël Coward, Quadrille, act 1, scene 2
