I`d like to tell you about my summer holiday. I went to the village to my granny. It was interesting place and it was warm every day. I went to the village with my family. We got there by train. When I arrived, I met my old friends there.
There was a beautiful river near the forest. The water was very warm, so I went to the river every day. Then I helped my granny with the garden. I liked it very much. I think it was my best summer holiday.
