How does Mrs. Pearson teach her children to be responsible adults?

First she scolds them for their guffawing and giggling. Then she has a dig at their lifestyle. They just come in, ask for something, go out again and then return as there’s nowhere else to go. When Doris and Cyril boast of doing their work all day Mrs. Pearson tells them that she has also done her eight hours work. She threatens to have two days off at the weekend.
