They Don't Say That Here!

If you're going to write a book, or a series of books, set in Tennessee (say...Ellery, TN?), you may want to get an American, perhaps even a Southern, editor. They won't miss phrase like "have a lie-in" or "in hospital" ---I promise you, no one in Tennessee says it like that! 

Those are just the glaring errors that take a reader completely out of the story...which tends to ruin the sheer pleasure of reading. Boo.
