Why you look so gloomy? What are you looking for?

My dissertation. I put it somewhere last night, and I can't find it now.

Did you finish typing it yesterday?

Yes, I kept on typing until midnight, but it's lost.

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?

Yes, but there's nothing inside the drawers or on the desk.

How about the shelf?

I've searched everywhere. Where on Earth did I put it?

Don't get upset over it. At least you have another week to go.

I've been working on it for a whole month and it's too late for write another. Just think of all my hard work that goes for nothing. How could I do such a thing?

Cheer up. What I meant was that you can find it sometime during the week. There's no need to write a new one. Oh, what's this? Is this you dissertation?

Let me see. Yes, that's it. Where did you find it?

You put it among these journals.

My poor memory. Thank you very much!
