" Sidney was intriguing. But she made Anna feel uncomfortable. She had that bright, mocking cynicism that challenged her in some way. Sidney was irritating, almost aggressive; but also there was that curious farouche sort of nervousness about her. And her attractive, one-sided smile that you couldn't quite trust in, and which promised so much; which, perhaps, was the token of a rare inward warmth. There was nothing easy about her. She was sharp, and stinging and stimulating and would need living up to; she would keep you on your mettle. "
