City] country] dear richard thank you for your letter.i haven't writen you because i was busy enough with my scholastic project. in your letter you asked me about my life. firstly we've got a huge house with two floors and a backyard as well.as for me i've got a cozy room which is used by me lots of time a day. i guess i spend much time at the room because i like to play computer games. in our districts you are able to do lots of things due to we live in the central part of the city, i think it's well for me. keep in touch! best wishes, [your name] написал вариант как в егэ но без обратных вопросов и из-за неопределенных вопросов немного смазано, но думаю в школе пойдёт.
