Debbie: Hello?
John: Hi, Debbie. This is John. I'm calling from Australia.
Debbie: Australia?
John: I'm at a conference in Sydney. Remember?
Debbie: Oh,right. What time is it there?
John: It's 10:00 P.M. And it's four o'clock there in Los Angeles. Right?

Debbie: Yes - four o'clock in the morning.
John: 4:00 A.M.? Oh, I'm really sorry.
Debbie: That's OK. I'm awake . . . now.
