"Because you are so nice to me, I think," she replied softly; and then was afraid lest she had said too much. But he nodded, and seemed to understand; and she dropped her eyes suddenly and began crumbling her bread. "What makes you so nice to me, I wonder," she continued in the same tone. This time he became matter-of-fact. "The natural order of the universe, I suppose. Man was created to look after woman, and woman to look after man; don't you think so?" She understood him well enough, by now, to know when to take her tone from him. "At all events, it saves Providence a lot of trouble," she said; and they laughed together. Their lunch was a success; and Paul smiled at her woe-begone face when the black coffee had been brought, and she was beginning slowly to remember that there was still such a place as number ten, Queen's Crescent, and that it actually existed in the same metropolis as the one that contained this superb restaurant. "It is nearly over, and it has been so beautiful," she sighed. "Nonsense! it has only just begun. It isn't time to be dull yet; I'll tell you when it is," said Paul briskly; and he called for a daily paper. "What do you mean?" gasped Katharine, opening her eyes wide in anticipation of new joys to come. "We're going to a matinee, of course. Let's see,--have you any choice?" "A theatre? Oh!" cried Katharine. Then she reddened a little. "You won't laugh if I tell you something?" "Tell away, you most childish of children!" "I've never been to a theatre before, either." They looked at the paper together, and laughed one another's suggestions to scorn, and then found they had only just time to get to the theatre before it began. And she sat through the three acts with her hand lying in his; and to her it was a perfect ending to the most perfect day in her life. He took her home afterwards, and left her at the corner of the street. "I won't come to the door; better not, perhaps," he said, and his words sent a sudden feeling of chill through her. They seemed to have fallen back into the conventional attitude again, the most appropriate one, probably, for Edgware Road, but none the less depressing on that account. "You are not going to be sad, now?" he added, half guessing her thoughts. She looked up in his face and made an effort to be bright. "It has been beautiful all the time," she said. "I never knew anything could be so beautiful before." "Ah," he said, smiling back; "it is the first day of your first holidays, you see. We will do it again some day." But she knew as he spoke that they never could do it again.
