Pygmalion discussion

I read this book on my "behind the scenes" class. It is describe Eliza who is from a countryside and sell the flower on a street of London. Mr. Higgins is the hero in this book and he is a linguistician. Eliza has a rural accent. Mr. Higgins was bet with his friend after they met with Eliza that is he can make Eliza become a noble during 6 months. But at the end of the story, Eliza was heard that Mr.Higgins helps her it is because of he was bet with his friend so she is very sad and she left him.
