We've just moved into a new house.
Really? Congratulations.
Thank you. I think we want to buy a new television set.
What kind of television do you want to buy?
A color TV set, of course. But I'm not sure about the size. Maybe we should buy a big one. If we buy a small one, we might have to exchange it in a few years for a bigger one. That would be a waste of money. What's your opinion?
In my opinion, I don't think it's necessary to buy a very big one.
Any particular reason?
Yes, as far as I know, your living room isn't very big. If you put a very big television there, it will be bad for your eyes. Besides, a small TV set can still pick up the same programs.
Hmm...That's quite true. I'll think about it.
You'd better decide quickly. Prices may go up soon.
