What makes Mrs. Higgins shout " Oh, men! men!!! men!"(p.111, l.21/22)
When Mrs Higgins cries out " Oh, men! men!", she's quite exasperated with her son's insensitive behaviour towards Eliza. She thinks the two mature and sedate individuals have acted pretty immaturely in handling Eliza. Like all men enamoured by women, these two confirmed bachelors have enjoyed the beautiful Eliza's company; laughed at her ridiculous anecdotes and behaved more like children playing with a toy; yet like most men haven't given a second thought of what is to become of her after the experiment is over. Though Higgins prides himself on having given Eliza all the advantages of good education, he fails to see how that itself would become a stumbling block for a woman without the means required to support the kind of lifestyle he has unwittingly made her accustomed to. Higgins is positive he would be able to find "some light employment" for her. He doesn't realize that Eliza is bred to no calling and having acquired the kind of education that she has, she becomes a misfit in the world because, neither can she go back to her trade, nor does she have the resources to support and maintain herself as a lady of high social standing. He lacks the farsight that his mother has and Mrs Higgins feels sorry for the poor flower girl and in her helplessness cries out the way she does.
