What is happening this day and who is there?(Act3) [I don't think I'm being clear enough to what I'm referring to, so if you don't have an answer thank you for trying]

A few months later, Higgins's mother (Mrs. Higgins) is writing letters in her drawing room when she is interrupted by her son. She scolds him for turning up during her "at-home day," the day when she receives guests. Mrs. Higgins claims that her son scares off her guests.

Higgins explains his bet with Pickering over Eliza and says that she is coming to the house to try out her accent. Mrs. and Miss Eynsford Hill are shown in, and they are the same mother and daughter who were waiting for a cab at the beginning of the play. Higgins recognizes them, but he cannot figure out where he has seen them before. Freddy also arrives. Miss Eynsford Hill tries to flirt with Mr. Higgins, but he rails at the company (including himself) for having no knowledge of science, philosophy, or poetry--merely knowing how to act in society.
