The Importance of Being Earnest
Algernon: Yes; but this isn't your cigarette case. This cigarette case is a present from some one of the name of Cecily, and you said you didn't know any one of that name.
Jack: Well, if you want to know, Cecily happens to be my aunt.
Algernon: [Retreating to back of sofa] But why does she call herself little Cecily if she is your aunt and lives at Tunbridge Wells? [Reading] 'From little Cecily with her fondest love.'
Jack: [Moving to sofa and kneeling upon it] My dear fellow, what on earth is there in that? Some aunts are tall, some aunts are not tall. That is a matter that surely an aunt may be allowed to decide for herself. You seem to think that every aunt should be exactly like your aunt! That is absurd! For Heaven's sake give me back my cigarette case. [Follows Algernon round the room.]
Algernon: Yes. But why does your aunt call you her uncle? 'From little Cecily, with her fondest love to her dear Uncle Jack.' There is no objection, I admit, to an aunt being a small aunt, but why an aunt, no matter what her size may be, should call her own nephew her uncle, I can't quite make out. Besides, your name isn't Jack at all; it is Ernest.
Jack: It isn't Ernest; it's Jack. (I.62-69)
Jack: […] When one is placed in the position of guardian, one has to adopt a very high moral tone on all subjects. It's one's duty to do so. And as a high moral tone can hardly be said to conduce very much to either one's health or one's happiness, in order to get up to town I have always pretended to have a younger brother of the name of Ernest, who lives in the Albany, and gets into the most dreadful scrapes. (I.83)
Algernon: You have invented a very useful younger brother called Ernest, in order that you may be able to come up to town as often as you like. I have invented an invaluable permanent invalid called Bunbury, in order that I may be able to go down into the country whenever I choose. Bunbury is perfectly invaluable. If it wasn't for Bunbury's extraordinary bad health, for instance, I wouldn't be able to dine with you at Willis's to- night, for I have been really engaged to Aunt Augusta for more than a week.
