How we cite our quotes:
MRS. HIGGINS. Be quiet, Henry. Colonel Pickering: don't you realize that when Eliza walked into Wimpole Street, something walked in with her?
PICKERING. But what?
MRS. HIGGINS [unconsciously dating herself by the word] A problem. […]
MRS. HIGGINS. No, you two infinitely stupid male creatures: the problem of what is to be done with her afterwards.
HIGGINS. I don't see anything in that. She can go her own way, with all the advantages I have given her. (3.248-255)
Mrs. Higgins is concerned that her son and Pickering have been short-sighted, and failed to acknowledge the full extent of their task. Eliza's problems, like her personality, are multifaceted.
