Dear John,
Thanks for your letter. Sorry that I haven't been written for a long time, I was busy with the preparation for exams. (24 сл)
You asked me about youth organisations in my school. Well, we have an acting group, for instance. These are guys who take part in all the school concerts and even once they were invited to the regional singing contest. What a pride! As for me, I don't take part in their activities, unfortunately. However, I'd really love to try because I've always dreamed of becoming an artist. (67 сл)
Looking forward to hearing from you!
Best wishes,
