Dear Sigmund Friend

My name is Simon and I am a Grade 9 student. I am crazy 　31　 football! I love 　32 　football, reading about football, and of course, playing football. My dream 　33 a great football player. However, my love of football has become a big problem, and I would like your 　34　 .

I have 　35 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 for three hours or more and forget when to stop. Then I 　36　 trouble at home because my parents do not allow me to play outside after 6 p.m. I really do not understand why they are so strict. I feel stressed and angry　　 37　 . I believe it is important for us to spend some time on our hobbies. They can help us relax and make our lives 　 38　 .I wish I could have my parents’ 　39　 .

Is it bad to stay out late to play football? Should I spend less time on it? I really do not know　 40　 . Can you please advise me how to achieve a balance between my schoolwork and my hobbies? Thanks a lot.

Best wishes

Simon
