Yvette, also, could not sleep. Like her mother, she leaned upon the sill of the open window, and tears, her first bitter tears, filled her eyes. Up to this time she had lived, had grown up, in the heedless and serene confidence of happy youth. Why should she have dreamed, reflected, puzzled? Why should she not have been a young girl, like all other young girls? Why should a doubt, a fear, or painful suspicion have come to her? She seemed posted on all topics because she had a way of talking on all subjects, because she had taken the tone, demeanor, and words of the people who lived around her. But she really knew no more than a little girl raised in a convent; her audacities of speech came from her memory, from that unconscious faculty of imitation and assimilation which women possess, and not from a mind instructed and emboldened. She spoke of love as the son of a painter or a musician would, at the age of ten or twelve years, speak of painting or music. She knew or rather suspected very well what sort of mystery this word concealed;--too many jokes had been whispered before her, for her innocence not to be a trifle enlightened,--but how could she have drawn the conclusion from all this, that all families did not resemble hers? They kissed her mother's hand with the semblance of respect; all their friends had titles; they all were rich or seemed to be so; they all spoke familiarly of the princes of the royal line. Two sons of kings had even come often, in the evening, to the Marquise's house. How should she have known? And, then, she was naturally artless. She did not estimate or sum up people as her mother, did. She lived tranquilly, too joyous in her life to worry herself about what might appear suspicious to creatures more calm, thoughtful, reserved, less cordial, and sunny. But now, all at once, Servigny, by a few words, the brutality of which she felt without understanding them, awakened in her a sudden disquietude, unreasoning at first, but which grew into a tormenting apprehension. She had fled home, had escaped like a wounded animal, wounded in fact most deeply by those words which she ceaselessly repeated to get all their sense and bearing: "You know very well that there can be no question of marriage between us--but only of love." What did he mean? And why this insult? Was she then in ignorance of something, some secret, some shame? She was the only one ignorant of it, no doubt. But what could she do? She was frightened, startled, as a person is when he discovers some hidden infamy, some treason of a beloved friend, one of those heart-disasters which crush.
