What is Mrs. Pearson’s problem? What advice does Mrs. Fitzgerald give her?

Mrs. Pearson’s problem is that her family takes no notice of her, though she is extremely fond of them. She runs after them all the time, takes their orders as if she was the servant in the house. She stays at home every night while they go out enjoying themselves. Mrs. Fitzgerald advises her that she should assert herself as the mistress of the house if she wants them to treat her properly.
