Doubting his senses, yet fearing to reassure himself, Pygmalion kissed the statue.In an instant the maiden’s face bloomed like a waking rose, her hair shone golden as returning sunlight; she lifted her ivory eyelids and smiled at him.

Oh, when I think of myself crawling under your feet and being trampled on and called names, when all the time I had only to lift up my finger to be as good as you, I could just kick myself.HIGGINS [wondering at her]. . . . By George, Eliza, I said I’d make a woman of you; and I have. I like you like this.LIZA. Yes: you turn round and make up to me now that I’m not afraid of you, and can do without you.
