I will gladly tell you the history of my spectacles,” began Titbottom. “It is very simple; and I am not at all sure that a great many other people have not a pair of the same kind. I have never, indeed, heard of them by the gross, like those of our young friend, Moses, the son of the Vicar of Wakefield. In fact, I think a gross would be quite enough to supply the world. It is a kind of article for which the demand does not increase with use. If we should all wear spectacles like mine, we should never smile any more. Oh--I am not quite sure--we should all be very happy.”
