My summer holidays are the best days in my life. Last summer, I flew to the capital of our Motherland,to Moscow.In Moscow I stayed with my relatives and walked around the city. After that I went to Belarussian city Vitebsk by train.There I visited the Slavonic Bazaar, went to a Sergey Lazarev's concert.I really like to visit these places. And perhaps these are one of the best days in my life.
Berlin and Aidar are going to camping in the forest.
