Dear Sigmund Friend

My name is Simon and I am a Grade 9 student. I am crazy   1   football! I love   2   football on TV, reading about football, and of course, playing football. My dream is to be a great football   3 . However, my love of football has become a big problem, and I would like your   4 .

I have many friends, and we always play football together at school or in the park after school. We like staying out late to play football. We often play  5  three hours or more and forget when to stop. Then I get into trouble at home because my parents do not   6   me to play outside after 6 p.m. I really do not understand why they are so   7 . I feel stressed and angry from time to time. I believe it is important for us to spend some time on our hobbies. They can help us relax and   8  our lives more interesting. I wish I could have my parents’ supports.

Is it bad to stay out late to play football? Should I spend less   9   on it? I really do not know    what to do. Can you please advise me   10  to achieve a balance between my schoolwork and my hobbies? Thanks a lot.

Best wishes

Simon
