Dear Sasha,
Thank you for your letter.
Happy 8th Match! I wish you happiness and a lot of good.
In your letter you asked me how I spend my free time. Well, I like reading books and go for a walk with my friends. I usually go to the cinema with my friends. As for the books I like, my favourite genre is fiction books.
I go in for sports. Sports is good for health but I don't like it because it's boring. So I do спорт activies only in PE lesson.
As for the clubs at school, I go to the Art club on Mondays. It's very interesting. I don't want to join any other clubs because if I do, I won't have enough time for my homework.
I have to go now. Look forward to receiving your reply.
Best wishes,
Julia
