26/09/19 Zhanaozen, Kazakhstan. Dear Albina, I was very glad to get your letter. Sorry, I haven't written for so long , because I was busy. In your letter you asked me about a kind of tour. As for me , I prefer beach holiday. It's cool to be near the sea, because you can relax. I'm going to spend holiday in my dacha. There are my friends and I do for a walk with them. Spending time with my friends makes me happy. I'm happy that you've joined a club. What do you do there? Are there many people? Do you watch there films or serials? I'm sorry. I have to go. Best wishes, ( пишешь свое имя на английском , точку не ставь после имени)
