Dear Ben,
Thank you for your letter. Sorry, I couldn't reply straightway, I was busy with my schoolwork.
So, I'll try to answer the questions you asked me in your previous letter. As for me, I use computer to surf in the internet and to chat with my good friends. Frankly speaking, I spend about 5 hours a day working on my computer. Also, in my leisure time I love listening to music and of course I read a lot of exciting and interesting books.
Sorry, I have to go now. I promised my mom to go shopping with her.
Write back soon.
Best wishes,
Katya (твоё имя, ясно дело, без запятой)
