Dear John,
Many thanks for your letter. It was great to hear from you!
I should agree with you, not many people like to read nowadays. I think that teenagers read much less than their parents did because the era of the internet has come, and we need to process a lot of information, so there is simply no time and energy for reading. But I really like reading. I like fantasy books, my favourite is “The Hobbit”. In my free time I try to spend as much time with my friends as possible. I think it's important to stay contacted.
Anyway, I'd better go now. I've got lots of homework to do tonight. I will write you again as soon as possible.
Your friend,
(ТВОЕ ИМЯ НА АНГЛИЙСКОМ).
