Explain Eliza and Higgins’ conversation about what she is “fit for” now. (Act 4)

Higgins returns, looking for his slippers again, and Eliza throws them at him. Eliza angrily explains that she does not know what to do with herself, now that she has won the bet. Higgins says that she is overreacting. He tells her that after she sleeps she will feel better. He adds that she is quite attractive, so maybe she could marry after all-perhaps his mother could find someone genteel for her to marry. Eliza responds that she was above selling herself when she was a working-class woman; she merely sold flowers instead of her body. Higgins replies that her moral judgment against marriage is unfair.
