"It is a misfortune for Anglo-American friendship that the two countries are supposed to have a common language. A Frenchman in America is not expected to talk like an American, but an Englishman speaking his mother tongue is thought to be affected and giving himself airs. Or else he is taken for a German or a Dutchman, and is complimented on his grammatical mastery of the language of another nation."
