There were two old people—a man and a woman, peasants, both of them very poor, very humble, so frightened that they could breathe only with their mouths open; and so soon as they were inside the circle of guests, they had dropped to their knees. The other member of the smith's party would have done the same had he permitted. This was a girl of twenty or so, likewise a peasant, healthy, painfully abashed, but otherwise not notable.
