I'm looking for a plain blue sweater.
How about this one?
Yes, that's nice. Could I try it on?
Certainly. The fitting rooms are over there.
David's going to meet us at the club around six.
Good. How will he get there? I don't think driving is a good choice in the rush hour.
David said he'll take the underground. What about us?
Let's go by bike.
Jane, wait a second. I'm going with you.
Okay. I'm going to Professor Wang's calligraphy class.
I know. It's in the chemistry building, right? My biology class is in the same building.
Is there anything else you want?
No, thank you. By the way, in case there's a problem with this air conditioner, can I return it?
Yes, but you must return it within thirty days.
Stop checking emails! We are in the middle of a vacation!
Okay! One more minute and I'll switch it off.
