[speaker001:] Hello? This is Steven. I'd like to speak to Mr. Brown, please.
[speaker002:] I'm afraid he is not in at the moment.
[speaker001:] Then what time do you think he will be in?
[speaker002:] I suppose he won't come back until 6 p. m. By the way, do you want to call later, or would you like to leave a message?
[speaker001:] I'd like to leave a message. Please ask him to give me a call as soon as he returns. He has my number.
[speaker002:] Okay, I'll do that.
[speaker001:] Thank you. Bye-bye!
[speaker002:] You're welcome, bye!
