For some time she observed a great yellow butterfly, which was opening and closing its wings very slowly on a little flat stone.
"What is it to be in love?" she demanded, after a long silence; each word as it came into being seemed to shove itself out into an unknown sea. Hypnotized by the wings of the butterfly, and awed by the discovery of a terrible possibility in life, she sat for some time longer. When the butterfly flew away, she rose, and within, her two books beneath her arm returned again, much as a soldier prepares for battle.
