Mrs Brown had a good friend named Mary. One day, Mrs Brown invited Mary to have dinner with her"and"her husband. At twenty past five, Mr Brown came back from work. He found that his wife was not happy. “What’s the matter with you, dear?” he asked. “I’ve made a big mistake, my dear,” she said, “I’ve asked Mary to come"and"have dinner with us this evening.” “That’s a good idea"and"there’s nothing to worry about,” Mr Brown said, “I’m sure we will have a good evening together.” “But there’s not enough food at home. I asked you to get some meat on your way home three days ago but you forgot.” “Oh, dear!” said Mr Brown.
