Now I want to tell you about my holidays. I was very happy to have holidays!  The weather was fine so my friends and I went for a walk every day. It was fun! We went to the cinema and to the swimming pool.Then I spent a few days in the country where my grandfather and grandmother live. It was great. I drank milk and ate a lot of tasty food which my granny prepared for me. I have many friends in this village because I go there every holidays. We played tennis every day! We went to the forest to gather mushrooms or just for a walk. When the weather was rainy and windy I played computer games and watched TV. But  holidays were over and I returned to the city again.  I liked my holidays very much, but I love to go to school too.
