cup-and-ball

When I was at Motiers, I used to employ myself in making laces with my neighbors, and were I again to mix with the world, I would always carry a cup-and-ball in my pocket; I should sometimes play with it the whole day, that I might not be constrained to speak when I had nothing to discourse about; and I am persuaded, that if every one would do the same, mankind would be less mischievous, their company would become more rational, and, in my opinion, a vast deal more agreeable; in a word, let wits laugh if they please, but I maintain, that the only practical lesson of morality within the reach of the present age, is that of the cup-and-ball.
