Quote from Rose in The Impotence of Being Ernest
Rose: Oh, I can't do it. I can't ask him to go away with me. I've never learned how to be aggressive. Blanche: Honey, it's as easy as riding a bicycle. Rose: I never learned how to ride a bicycle. Dorothy: It's as easy as falling off a bicycle. Rose: Really? Well, that is easy. Thanks, Dorothy. [exits] Dorothy: It was just a hunch.
