Nick's usual working day
Hi, nice to meet you all! My name is Nick Price. I am a freshman at the College of Business at Western Carolina University. It is a very small school situated in the mountain region of North Carolina. I am not from North Carolina myself. I was born in Vermilion, Ohio, in the suburbs of Cleveland. But my grandpa and grandma live in North Carolina. And I like mountains more then plains. My family is not very rich that is why I can't afford to live on campus. But it is a rule, that every student must spend his or her freshman year on campus. To cover some of expenses I've got to work part-time on the campus. I work in cafeteria. Now let my tell you about my usual working day. I wake up at seven in the morning. My alarm clock is tuned on to my favorite radio station. My roommate Todd Hall is a football player. He jogs every morning at 6.30. He is still out jogging when I get up. First I take a cold shower and brush my teeth. Then I dress myself up and rush to my work to the University cafeteria. I wash dishes and clean tables. It is not a very interesting job, I know that, but soon I'll be a waiter at the small Italian Restaurant and will earn more. My boss Suzie is a very strict lady but she is very nice when I do my job properly. My first class starts at 11.15. The professor is never late for his classes. The lecture hall we sit in has about 100 seats. WCU (Western Carolina University), like I said, is a very small school. But I think that it is one of the best schools of business in North Carolina. At 2 PM I eat lunch at school cafeteria. The food is free for me because I work there. I am a vegetarian and I don't like drinks with caffeine. I prefer cool filtered water or juice. Then I have two more classes. I need to go to the library right after the classes to do my homework. There I meet my friends and we talk. Twice a week I play basketball with my friends. I swim once a week. Usually after library we go out to the cafe or just sit outside and talk. I have dinner at 6 PM at the little Chinese restaurant not too far from the dormitory. Or I cook myself in the kitchen in my dorm. My favorite food is salami pizza and potato salad. After a dinner I watch TV or play ping-pong with my friends. When it is Friday, we go to see the football game. I spend most of my weekends visiting my grandmother and my grandfather. There are always glad to see me and take me out for picnics and golf. I usually read before I go to bed. It calms me down after the long day. My favorite author is Stephen King. Well, I guess that's enough. See you later!
