dialogue: W: I'm fed up with sitting on packing cases, Joe. Don't you think we should buy at least two chairs? M: Do you know how much new chairs cost? One cheap comfortable armchair is eighty pounds. W: Yes, I know. It's terrible. But I have an idea. Why don't we look for chairs at a street market? I've always wanted to see one. M: All right. Which one shall we go to? W: Portobello Road, I think. There are a lot of secondhand things there. And we'll have to go tomorrow. It's only open on Saturdays. M: What time do you want to go? Not too early. I hope. W: The guidebook says the market is open from nine to six. It's a very popular market, so we'd better be there when it opens. M: Right. I'll set the alarm.
