Dear Jeff,
Thanks for your letter. I am sorry, I haven't answered earlier but I was really busy with my schoolwork.
I am so glad that you decide to write me. Unfortunately, I recently was sick too. I read interesting books, when I was in bed. I advise you to read books. For example, I like to read detective stories and horrors. It's very exciting. You can watch different films, play phone games or calls to your friends. You shouldn't miss.
Sorry, I have to go. My mother would like me ti help her.
Drop me a letter when you can.
Take care,
Karina
