My Friend and his/her Family!

I have got a friend. His name is Nikita. He is ten years old. He is my classmate (одноклассник). I do not think he studies very well. He likes to play very much, but he does not like to do his homework. We study many subjects at school, but i think he likes only Drawing and Physical Training lessons.His family is not very large. He has got a father, a mother and a sister. His father is a manager. He works in an office. He is usually very busy. His mother is a teacher of literature. She works at school. His sister Polina doesn't go to school, she is only three.Nikita and I are good friends. We spend much time together playing different games and going for a walk together.
