Hi Mark,
Thank you very much for your interesting letter. I glad to hear about you activities. Sorry, I haven't got any time to answer for your questions. I have been busy at school.
I'll be happy to answer your questions. Well, yes, I do sports every day. The most popular spots with teenagers in my region are football and basketball because they are very interesting and we can learn how to work in group.
I must finish now, because I have to do my homework. Write back soon,
Best wishes,
Nick
