Dear George,
Thanks for your email. I haven’t heard you for ages.
I’ve got a best friend whose name is Sergey. He’s sixteen. He’s quite tall for his age and slim. Seryozha is patient, optimistic, easy-going and sociable. He has a lot of hobbies. He is a good swimmer. Also he’s fond of playing the guitar. Now he's a student of Moscow College. He’s going to become an engineering technologist. Last summer we walked much together, but a school year has just begun and we both have a little free time. If we find the time, we meet up. That’s all about my friend.
Where are you planning to do on your winter holidays? How do you plan to celebrate New Year? What kinds of winder sport do you do? Have fun!
Yours,
