M: Why? What's the matter? I want to read the paper.
W: If we turn on too many lights, all the electricity in the house will go off.
M: Now who told you that?

W: I had to go to his home and ask for help today.
M: What was wrong?
W: When I turned on the washing machine, all the lights went out.
M: Well, did he take care of it for you?

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.
