“HIGGINS [grinning, a little taken down] Without accepting the comparison at all points, Eliza, it's quite true that your father is not a snob, and that he will be quite at home in any station of life to which his eccentric destiny may call him. [Seriously] 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.

HIGGINS [irritated] The question is not whether I treat you rudely, but whether you ever heard me treat anyone else better.
LIZA [with sudden sincerity] I don't care how you treat me.”
