Nan felt that she had been driven into a corner, and that there was but one way out of it. In spite of her strong desire to go with the girls, she had determined to stick to her resolve to stay behind. She had hardly known why she had tried to avoid them all these days. But now she knew. It was because she was afraid they would shake her resolution. Once she would have called herself cowardly for trying to spare herself such temptation, but now she knew better; she saw she had been simply wise. It would not have been brave, but merely reckless, to have done otherwise. She had known ever since Miss Blake spoke that she was free to do as she pleased. That she was held by no promise; that she was compelled by no stronger claim than Miss Blake's disapproval, which might be, after all, only a groundless personal prejudice, she thought. She hardly realized why she felt bound to obey. And now along came Ruth to prove that there were other claims outside Miss Blake's. She remembered perfectly having said that Ruth could count on her. Here was a very definite promise, although it had been made in half-ignorance, and she understood clearly that Ruth meant to make her keep it. Then, again, she was directly responsible for Louie's disappointment, and this seemed to her, as Ruth had intended it should seem, a compelling conclusion. If she had been older her reasoning would not have stopped here, but, as it was, she perceived only two sides to the question, and this that Ruth had just presented seemed infinitely more convincing than the one Miss Blake had tried to make clear to her. Ruth's logic she could understand; the governess' seemed vague and incomprehensible. In one case she had been coerced into making a promise from which she had later been absolved; in the other she had given her word of her own free will, and she was being stoutly held to it. There were other influences at work, but Nan did not know it. She honestly believed she was waiving all considerations but those with which her duty was concerned, and she thought she had done so when she broke out with a sort of impatient groan: "Oh, dear! I never saw such a tangle!" "Well," returned Ruth grimly, "I don't know anything about that, but whatever it may be, I've got the strong end of the line and I mean to hold it. You've just got to go and that's all there is to it." Nan gave a rueful laugh. She more than half-liked to have Ruth leave her no alternative. It somehow made her seem less responsible to herself. If the decision were taken out of her hands she could not be held accountable and--the enjoyment would be there all the same. "I wish you'd let me off, Ruth," she protested weakly, as a sort of last sop to her conscience.
