There was once an old woman who went begging. Whenever she received alms, she would say, "May God reward you."
One day, the beggar-woman came to a door where a friendly rogue of a boy was warming himself by the fire. Seeing the old woman shivering by the door, the boy kindly said, "Come, old mother, and warm yourself."
She came in but stood too close to the fire, causing her old rags to catch flame without her notice. The boy saw it happen but did nothing to put out the fire. Should he not have put it out? If he had no water, he should have wept streams from his eyes to extinguish the flames.
