Hi my dear friend. How are you? I will be so happy if you say to me something about your country, friends or family. Now I can say to you about mine. 

There are three people in my family: My parents and I.   We are very close family.  We live in the big country ( Russia) . I love my country and my city ( Moscow) . 

I have got a best friend. Her name Elena. She is very friendly, kind and brave girl.

Well, thats all that I wanted to say. I hope that you will answer.  Bye.
