Correctness is simply not a value any working writer would even recognize as important. Joan Didion, one of the greatest prose stylists of the last fifty years, says: “Grammar is a piano I play by ear, since I seem to have been out of school the year the rules were mentioned. All I know about grammar is its infinite power. To shift the structure of a sentence alters the meaning of that sentence, as definitely and inflexibly as the position of a camera alters the meaning of the object photographed.”6
