[Q]: M: Certainly. The idea is not to have a house full of different things. This is a complete home system. It will make people's lives easier. W: OK! So tell me how this house will make my life easier? M: When you arrive at the front door, you won't need a key. The door will open with a touch of your finger. You'll be able to call your refrigerator when you're at the grocery store and find out how much you need to buy. Isn't it wonderful? W: Can I call the washing machine as well? M: Sure. But you won't need to. The house comes with a robot. It is programmed to clean the house and do the washing. W: What does it cost? M: A million dollars. W: A million dollars! It will be the 22nd century before I can afford to buy one! What was said before this conversation?

W: But yesterday afternoon she told me that she would go home this Saturday. M: What happened? W: She said that her mother was ill and stayed in the hospital, and therefore she wanted to go home to see her. M: I am sorry to hear that. Well, What do you think? Should we take some food? W: That sounds great. Maybe we could have a picnic on the beach. Then let's take some sandwiches, chips, and uh...some salad as well. M: We should also take some drinks like Coke and beer. W: Good. In addition, we had better pack beach towels and sun cream. M: OK. Please don't forget to give me a call and let's go down together. What was said before this conversation?
