   John is my best friend. We live in the same building. We study in the same school but not in the same class. We often play football together after school. We have been good friends for two years.
   John is tall and strong with black hair. He has a round face, a small nose and big, brown eyes. I like his eyes because they are always bright and smiling.
   John is always friendly and helpful. When I feel bored or unhappy, he tells me funny jokes and makes me laugh. He'll give me help when I need.
