Why do 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 it until midnight , but it is 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 is 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 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 ?
