My dear friend, 
I'm sure you'll be surprised at receiving a
letter from a man who had never seen and did not know, so first of all I
introduce myself and tell you about themselves and their school.
My name is Vlad. I am 14 years old. I'm in 8th
grade in high school № 2 of "Balakovo." Three-storey school. In our
school there is a large sports hall. There are different classes of physical
education and sports competitions. In the hall we find holidays. Classrooms are
large and beautiful. The school has very good teachers. Each of them is always
interesting a lesson.
I'd really
like to hear about your school and your interests and want to congratulate you
on coming New Year soon.
