Dear Masha ,
My summer holidays were very interesting . I spent them very fast and fun. I visited the Republic Bashkorostan (Башкоростан) and the various resorts. Most of all I enjoyed is walked to ciy Ufa and swam in the salt lake. I liked to spend fan time at the cattage with my sister . I fist want to the city of Ufa , because this year I learned , that I have relatives.
Best wishes , Masha!
