Person1: Hello ! You have reached the offices of Maddox and McKnight , can I help you ?
Person2: Yes , my name is Max Richards . May I please speak to George Nelson ? I have already called several times . It seems I always catch him out of the office .
Person1: Oh , I'm sorry . Mr . Nelson is away at the moment . I'm sorry that you keep missing him while he is out of the office . Would you like to leave a message ?
Person2: I'm sorry , I didn't hear you clearly . Could you repeat that please ?
Person1: Certainly . Mr . Nelson can not take your call at the moment because he is away . He stepped out of the office for the whole afternoon and is not expected back until tomorrow morning . His schedule is very unpredictable at times , so the best way to reach him is to first make an appointment by email or text messaging .
Person2: Can I leave a message for him please ?
Person1: Of course , can you leave your name and number ? I'm sure Mr . Nelson will return your call as soon as he is able .
Person2: My name is Max Richards , my phone number is 898-3423 . Could you ask him to call me back as soon as he gets back , please ? I have a rather timely matter to discuss with him .
Person1: Can you tell me what it's about ? I can make a note of it , so Mr . Nelson is aware and prepared when he returns your call .
Person2: Yes , please let him know I would like to discuss the Girard case with him .

Person2: My dissertation . I put it somewhere last night and I can't find it now .
Person1: Did you finish typing it yesterday ?
Person2: Yes , I kept on typing it until midnight , but it is lost .
Person1: Don't worry about it . It must be somewhere in your room . Let's see where you put it . Have you searched your drawers and the desk ?
Person2: Yes , but there is nothing inside the drawers or on the desk .
Person1: How about the shelf ?
Person2: I've searched everywhere . Where on earth did I put it ?
Person1: Don't get upset over it . At least you have another week to go .
Person2: I have been working on it for a whole month and it's too late to write another . Just think of all my hard work that goes for nothing . How could I do such a thing ?
Person1: Cheer up ! What I meant was that you can find it sometime during a week . There is no need to write a new one . Oh , what's this ? Is this your dissertation ?
Person2: Let me see . Yes , that's it . Where did you find it ?
Person1: You ' Ve put it among these journals .
Person2: My poor memory . Thank you very much .
