What's the matter with Micawber?

"Among friends, sir!" repeated Mr. Micawber; and all he had reserved came breaking out of him. "Good heavens, it is principally because I AM among friends that my state of mind is what it is. What is the matter, gentlemen? What is NOT the matter? Villainy is the matter; baseness is the matter; deception, fraud, conspiracy, are the matter; and the name of the whole atrocious mass is—HEEP!"

Charles Dickens, David Copperfield (1850), ch. 49
