PAUL BROWN'S DAILY ROUTINE

Friday morning. The alarm clock goes off at 7. Paul usually gets up easily but not this time. It’s not simple to wake up so early if you go to bed at 3 in the morning. He can hardly open his eyes. Half an hour passes before Paul finally makes himself get up. He is still sleepy. He slowly gets dressed and looks out of the window. It’s drizzling1 and the sidewalk is wet. There’s nobody in sight2. The campus looks deserted. But Paul goes jogging every morning, whatever the weather3. He sighs4, puts on his sneakers and goes out. Twenty minutes later he comes back and takes a long shower. As usual jogging and a cold shower do him good. He is wide awake now. Paul looks at the clock. It’s 8.15. Time for breakfast. He goes to the kitchen to make coffee. A cup of coffee is always reviv¬ing5, especially after the party like yesterday’s. He smiles at the thought of that delicious birthday cake. But the smile vanishes6 the moment he remembers his schedule for today. He’s got three classes on Friday.
9.00–10.30 – German Class
11.00–12.30 – Political System of Germany
14.00–15.30 – German Literature
Anything else? An appointment with his tutor at 4 o’clock. He completely forgot! And there’s an essay to finish! When in the world can he do that? He suddenly remembers: lunch time (12.30—14.00). Well, he can’t afford7 a regular lunch today, just a quick snack. It gives him at least an extra hour more to finish his essay and get ready for the discussion. His tutor is always very critical of his students’ homework. You must know your subject well enough to answer his tricky questions.
8.50. Paul rushes out of the house. It doesn’t take him long to get to the college. So at 8.55 he is at the universi¬ty. All the students in his class are already there. They’re very glad to see Paul. And so is he. At 9 o’clock Mr Lewis comes in and the class starts. Mr Lewis’s classes are Paul’s favourite ones. Time flies quickly. He enjoys the class so much that the end of the class at 10.30 always comes as a surprise. 10.30–11.00. Coffee break. Paul and the other students go to a coffee bar to have a chat over a cup of coffee. 11.00. Back to another class. It’s rather difficult for Paul to concentrate on the subject, all the more so he doesn’t like it too much. It isn’t as in¬teresting as Mr Lewis’s German Class. Honestly Paul finds it boring.
12.30. Lunch time. Everybody hurries to the dining hall. But Paul doesn’t. At lunchtime he is at his desk in his room. So much work to do and so little time! Paul opens his essay book and starts writing. When he looks at the clock, it’s ten minutes past 2. He is late for the class but he feels great. His essay is ready! The thought is very comforting. Friday’s last class is German Literature, an¬other of Paul’s favourites. It’s always very interesting and instructive. After the class Paul has got half an hour to look through the essay and his notes. He is no longer afraid of the coming meeting. He feels sure of himself.
The session goes well. The students discuss their es¬says. The tutor makes some critical remarks but on the whole he’s quite pleased with their work. Finally he sets work for them to do and they part till next time. On his way home Paul drops in at the student pub. He takes a glass of beer and sits down at the table next to his friends. He looks around. The pub is crowded, as usual at this time. Everybody is laughing and talking. Loud music is playing. But nobody is dancing. It’s too early for that. Paul suddenly feels very tired. He says good-bye to his friends and leaves the pub. The thing is that there is a concert of a Spanish guitar player at the club at 8. Paul doesn’t want to miss it but he needs some rest. The con¬cert finishes at 11.30. When Paul comes back home, it’s nearly midnight. At long last the hard day is over! He takes off his clothes and goes to bed straightaway. 5 min¬utes later he is fast asleep.
