Analyze the tactics Eliza uses to rouse Higgins from his indifference. Do these tactics work?

Act Four also reveals an interesting power dynamic between Eliza and Higgins. Eliza most greatly resents the fact that Higgins views her success as his own, and she is infuriated by his idea that (like the mythological Pygmalion) he is the agent who created her. She views this claim as presumptuous and dehumanizing. Although by questioning Higgins about the jewelry she reminds him of the gap in class between them, she succeeds in making him angry. The ability to affect someone who holds himself maddeningly superior to her heartens her-she is glad to get "some of her own back" in this way. The relationship between the two now includes Eliza's pleasure at being able to hurt Higgins.

Eliza's actions at the end of the act remind the audience of the very real dilemma facing Eliza: what is she to do-stay or go? She mimicks Higgins, pleased that she has effectively gotten him angry, but she then begins to search, almost compulsively, for the ring that she has just discarded. This juxtaposition demonstrates that she still has feelings for Higgins, being not yet ready to throw away the sentimental token that he gave her. Searching for the ring also suggests an economic prudence on Eliza's part; her future is very unclear.
