W: When I turned on the washing machine, all the lights went out. M: Well, did he take care of it for you? W: Yes, but he said it would take a lot more work to do a really good job. M: What does he mean by a really good job? W: He said we need new electric wires throughout the house and a lot of other things. M: Did he tell you how much it would cost? W: Yes, about a thousand dollars. M: A thousand dollars? That's a lot of money. And just we need to get some work done on our car, too. What had gone wrong in their house?
