The Importance of Being Earnest
Cecily: Miss Prism has just been complaining of a slight headache. I think it would do her so much good to have a short stroll with you in the Park, Dr. Chasuble.
Miss Prism: Cecily, I have not mentioned anything about a headache. (II.21-22)
Cecily: Your brother Ernest…arrived about half an hour ago.
Jack: What nonsense! I haven't got a brother.
Cecily: Oh, don't say that. However badly he may have behaved to you in the past he is still your brother. You couldn't be so heartless as to disown him. I'll tell him to come out. And you will shake hands with him, won't you, Uncle Jack? (II.133-135)
Jack: [Slowly and hesitatingly] Gwendolen – Cecily – it is very painful for me to be forced to speak the truth. It is the first time in my life that I have ever been reduced to such a painful position, and I am really quite inexperienced in doing anything of the kind. However, I will tell you quite frankly that I have no brother Ernest. I have no brother at all. (II.348)
