[speaker001:] Why do you look so gloomy? What are you looking for?
[speaker002:] My dissertation. I put it somewhere last night and I can't find it now.
[speaker001:] Did you finish typing it yesterday?
[speaker002:] Yes, I kept on typing it until midnight, but it is lost.
[speaker001:] 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?
[speaker002:] Yes, but there is nothing inside the drawers or on the desk.
[speaker001:] How about the shelf?
[speaker002:] I've searched everywhere. Where on earth did I put it?
[speaker001:] Don't get upset over it. At least you have another week to go.
[speaker002:] 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?
[speaker001:] 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?
[speaker002:] Let me see. Yes, that's it. Where did you find it?
[speaker001:] You 'Ve put it among these journals.
[speaker002:] My poor memory. Thank you very much.
