Quote 22
LIZA. I had a good mind to break it. I didn't know which way to look. But I hung a towel over it, I did.
HIGGINS. Over what?
MRS. PEARCE. Over the looking-glass, sir.
HIGGINS. Doolittle: you have brought your daughter up too strictly.
DOOLITTLE. Me! I never brought her up at all, except to give her a lick of a strap now and again. Don't put it on me, Governor. She ain't accustomed to it, you see: that's all. But she'll soon pick up your free-and-easy ways.
LIZA. I'm a good girl, I am; and I won't pick up no free and easy ways. (2.308-313)
Doolittle equates wealth with laziness and wastefulness, and Eliza's own poverty seems to have instilled in her a sense of modesty. She will not so much as look in the mirror.
Quote 23
HIGGINS. The great secret, Eliza, is not having bad manners or good manners or any other particular sort of manners, but having the same manner for all human souls: in short, behaving as if you were in Heaven, where there are no third-class carriages, and one soul is as good as another. (5.197)
Higgins claims that the key to acting correctly is treating all people in the same way, acting as if class distinctions did not exist. He thinks that the only society that matters is the society of human souls, to which all men belong.
Quote 24
HIGGINS. There! As the girl very properly says, Garn! Married indeed! Don't you know that a woman of that class looks a worn out drudge of fifty a year after she's married. (2.105)
Higgins's views are stereotypical, but his comments do speak to the difficulties which come with raising a family in poverty.
