So the Amish have a different syntax than most Americans, as does Yoda ("always two there are!")but their grammar is correct.

Oliver Sacks was the first modern writer that I recognized by his writing. I had read an article of his in an old issue of Granta, but had not really noticed the author's byline. Shortly thereafter a friend loaned me "The Man Who Mistook His Wife For a Hat" and as I read it I felt like i recognized the writer's voice. I dug out the magazine article I had read and sure enough, it was Oliver Sacks.
