M: Hey, honey, why do you look so happy?
W: Great news. We just won $400 in the lottery.
M: Wonderful! How do we spend the money?
W: Well, I’m just thinking about it. Can we buy a new microwave stove?
M: With $400, we can afford the most expensive one.
W: Sure, but on second thought, don’t you think our washing machine is out of style?
M: Well, that’s still affordable. Hey, how about a camera? Look, we don’t have a camera; a camera will give us a lot of pleasure. Why should we spend all our money on family appliance instead of some luxuries?
W: Well, I don’t think it’s a good idea.
M: Ok, let’s think carefully about it.
W: Oh, How about something more exciting and attractive.
M: What is it?
W: Why not buy some jewelry? I need something that makes me more elegant and beautiful.
M: Well, in my opinion, you are pretty in your plain way.
W: Really, thank you, but I still insist on having a gold necklace.
