First of all I want to tell you that my best friend's name is Sahib 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.  Sahib 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.
