What social blunders does eliza commit

The event is revealed to have been a success, with Zoltan Karpathy having concluded that Eliza is "not only Hungarian, but of royal blood. She is a princess!" After the ball, Pickering flatters Higgins on his triumph, and Higgins expresses his pleasure that the experiment is now over ("You Did It"). The episode leaves Eliza feeling used and abandoned. Higgins completely ignores Eliza until he mislays his slippers. He asks her where they are, and she lashes out at him, leaving the clueless professor mystified by her ingratitude. When Eliza decides to leave Higgins, he insults her in frustration and storms off. Eliza cries as she prepares to leave ("Just You Wait" [Reprise]). She finds Freddy still waiting outside ("On the Street Where You Live" [Reprise]). He begins to tell her how much he loves her, but she cuts him off, telling him that she has heard enough words; if he really loves her, he should show it ("Show Me").
