Pygmalion

It's like teaching someone a foreign language. Although they have this new knowledge and capability, there's no forgetting or leaving their natural born roots behind. With Eliza, her wanting to work for a living and her personality just aren't accepted in this new world in which she's been trained to live in. This ends up leaving Eliza in the middle of two social classes, neither of which she fully fits the criteria for.
             Eliza in turn sees Higgins" offer to give her lessons in speech as an opportunity to not as much live in the high-class society, but as a way to enable her to present herself as a respectable young lady. Growing up on the streets, she has learned that what you receive in life is not something just handed to you. She believes in the work ethic, and wants nothing more than to be able to get a job at a flower stand, which hasn't been possible due to her street slang. Arriving for the first day at Higgins's house, Higgins treats her as nothing but an object in which he can throw around, a project. This arrogance and manner in which Higgins treats Eliza follows pattern through the entire movie, even up to the point when Eliza proves herself capable of high-class living. Here she proves Higgins to be a master scholar of phonetics, and still, in his mind, she's the poor flower girl from the streets. .
             There is a key moment in the story where Eliza walks into a room where Pickering and Higgins are having a conversation concerning Eliza and how they were glad the whole experiment was over. They both agree that Eliza could now have the chance to marry into a wealthy family and live the life of a respectable lady. Neither of the two ever acknowledges Eliza as she's standing in the room and gives the feeling that since the project was over, they had no more use for her. This event arises the birth of Eliza's independent spirit and ends up tossing it in Higgins face.
