First of all I want to tell you that my best friend's name is Igor and he is 15. He is the best person I have ever met. A few  words about his appearance. His height is nearly 149 cm. But he'd like to be a bit taller.  Igor has a round face as everyone has, a bit long nose and big cheerful grey eyes. His forehead is open.  His hair isn't very short but it's not long either. It is straight and black.  I think that he looks like his father. My friend is very active and creative, cheerful and curious. But the best thing is that he is reliable. We spend much time together. We go for a walk, we play tennis, listen our favorite music, play computer games, watch TV, do things which we like. I love my friend.   

Прежде всего, я хочу сказать вам, что моего друга зовут Игорь и ему 15. Он самый лучший человек, которого я когда-либо встречал. Несколько слов об его внешности. Его рост около 149 см. Но он хотел бы быть немного выше. 
У Игоря круглое лицо, как и у всех, немного длинный нос и большие радостные серые глаза.  Eго лоб открытый.   Его волосы не очень короткие, но это не длинные. Они прямые и  черные. Я думаю, что он похож на своего отца. Мой друг очень активный и творческий, жизнерадостный и любознательный. Но самое главное - он надежный. Мы проводим много времени вместе. Мы ходим гулять, играем в теннис, слушаем нашу любимую музыку, играем в компьютерные игры, смотрим телевизор, делаем вещи, которые нам нравятся. Я люблю моего друга.
