My holidays, as a rule, I spent with my grandmother in the village. I love to live there. Next to the house there is a small forest and a river.  We swam and sunbathed, walked in the forest, went hiking, had picnics and, of course,  I helped my grandmother in the garden. 
 August was the most interesting month. Finally, my dream came true, and my parents and I went to Moscow. It was great! Our relatives showed us the capital of Russia. It was the first time when I flew by plane! We ate out in a restaurant, walked around a park, visited many museums and saw a lot of  art exhibitions.The second half of August I was at home.
