I found most interesting when Eliza, Higgins and Pickering come home from the successful ball. The servants praise the excellent work of Higgins and Pickering and sing great hymns for them. Eliza is ignored by all the people and stands alone and isolated in a corner. Nobody says that Eliza did a great job and that not only the two men are responsible for the success. After that, all of them go to bed and don't recognize Eliza. Except Higgins who gives her the advice to switch off the light. This is again very frustrating for Eliza because she is treated like a servant even after her perfect performance at the ball.
