The Importance of Being Earnest
Lady Bracknell: To speak frankly, I am not in favour of long engagements. They give people the opportunity of finding out each other's character before marriage, which I think is never advisable. (III.86)
Jack: [Embracing her] Yes . . . mother!
Miss Prism: [Recoiling in indignant astonishment] Mr. Worthing! I am unmarried!
Jack: Unmarried! I do not deny that is a serious blow. (III.148-150)
