I have seen many people, who, while you are speaking to them, instead of looking at, and attending to you, fix their eyes upon theceiling, or some other part of the room, look out of the window, play with a dog, twirl their snuff-box, or pick their nose. Nothing discovers a little, futile, frivolous mind more than this, and nothing is so offensively ill-bred.
