[speaker001:] Hello. Can I talk to David?
[speaker002:] One second, please. [a few seconds later, the receiver comes back and says] Hello?
[speaker001:] Yes.
[speaker002:] I 'm sorry. David is out to lunch right now.
[speaker001:] Okay. I 'm his wife. Could you tell him to call me back when he returns?
[speaker002:] Sure. Does he know where to call you?
[speaker001:] Oh, thanks. Please tell him to call my cell-phone number.
[speaker002:] Ok, I will.
[speaker001:] Thank you very much.
[speaker002:] No problem.
