Bunbury

[...]

Jack. My dear Algy, I don’t know whether you will be able to understand my real motives. You are hardly serious enough. 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. That, my dear Algy, is the whole truth pure and simple.

Algernon. The truth is rarely pure and never simple. Modern life would be very tedious if it were either, and modern literature a complete impossibility!

Jack. That wouldn’t be at all a bad thing.

Algernon. Literary criticism is not your forte, my dear fellow. Don’t try it. You should leave that to people who haven’t been at a University. They do it so well in the daily papers. What you really are is a Bunburyist. I was quite right in saying you were a Bunburyist. You are one of the most advanced Bunburyists I know.

Jack. What on earth do you mean?

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.

Jack. I haven’t asked you to dine with me anywhere to-night.

Algernon. I know. You are absurdly careless about sending out invitations. It is very foolish of you. Nothing annoys people so much as not receiving invitations.
