I work nights. I get to work at 8 in the evening , and I finish work at 5.30 in the morning. When I get home, I'm not tired because it's getting light and I don't want to sleep. In fact, I feel energetic, and I usually go for a run. When I come back, I have a shower and change my clothes. Then I have breakfast , but I'm not sure if it's breakfast or dinner! After my meal I normally feel tired, so I go to bed at about 9. I always watch a film for an hour or so. I don't have an alarm clock, and I always wake up between 4 and 5 in the afternoon and usually read a newspaper. I get up about 6, then start getting ready for work. My job's great - we have long breaks, so if I'm tired, I can usually have a nap for 20 minutes or so, and then I feel much better. And at weekends I don't go anywhere - I just relax in front of the TV.​​
