MY FRIEND I have many friends. Most of them are my former classmates but my best friend, is Peter. He is fifteen. Now he is a student of a college. He is a good student because he-studies hard and is very diligent. He wants to become a good specialist and he is especially interested in computers. He often helps me with my English lessons and I'm graceful to him for that. Now I want to tell you about his appearance. He is rather tall and strong. He has an oval face, straight nose, dark-brown hair, blue eyes and a nice smile. People find him good-looking. Peter goes m for sports. He plays football and basketball well. His basketball team is very popular at the college. We made friends with Peter when he and his family moved to our house. We have very much in common: we like the same music, we both like reading. In general my friend is a very interesting person: he is intelligent and well-read. But the most important thing is that Peter is honest and kind. I can fully rely on him and trust everything to him. Peter has a great sense of humour and I like to spend my free time with him. I have another friend. Her name is Natasha. She is schoolgirl and she lives next door. I like her very much. She is a blonde with blue eyes, she is slim and pretty. Her hair is long and she has a nice complexion. I like all my friends very much. I think they are all my faithful friends.
