Dear friend,
I'm very glad to hear you again! 
On holidays I'm going to visit my grandparents. They live in a small country not far from Moscow. I'm going to spend a lot of time outside, for instance, I'm going to sunbathe and help my grandparents with their duties. So, my holidays are going to be exciting!
With love, *имя*.

Hello Mary it's me again! I haven't got much time but I still wanted to white you a letter. I just finished my school and I'm going to get reddy for those horrible exams! I'm not going to learn every thing but most of all. Oh well, I got to go see you bye!
