What is the reaction of Doris and Cyril to the unusual behaviour of their mother?

Both Doris and Cyril are astonished at the unusual behaviour of their mother. She has always been very kind and affectionate, meek and submissive. But now she is very cold and indifferent, and seems to be in a defiant mood. She has not bothered to get tea ready for them and asks them to help themselves. When Doris asks her to iron her yellow silk, mother refuses to oblige. She has not cared to put Cyril’s things out though she had promised that morning to look through them in case their was any mending. They are astonished to hear that mother, who has been running after them all the time taking their orders, now proposes to work forty hours a week and have two days off from household chores. They stand against to see her going to the kitchen to fetch stout of herself. As far as they know her she has never tasted stout. They thought that they had done something wrong and mother was offended with them. But now they realise there is something wrong with the mother. Doris thinks mother might have hit her head and got some violent shock, but her idea seems too far-fetched to Cyril. Nevertheless, they laugh to think how she would behave when Dad comes home.
