Dear friend, I’m really unhappy now because my parents always make me stay at home and study every night during the week. They say that I must study hard for my exams. But in my opinion, I don’t have to work so hard all the time. I have problems on weekends, too On weekends I can go out with my friends, but I have to be home before 20:00. It’s crazy! They don’t want me to go to parties, either. They say it won’t do good for my studies. What should I do? Can you give me some suggestions? Elizabeth
