After years in the making, the good people, well really just the one person, at grammarRULES brings you a new line of Politeness Plates. And who wouldn't agree that dishing on good manners would be very helpful right about now?
Best grammar story: Two sisters visit my booth at a local art show. They tell me their mother was on her deathbed. She tried to sit up and the daughters said,"Mother, please, lay down." Her last words to them were, "It's lie down."
