My best friend's name is Andrew. We've been friends since kindergarten. He is 15 years old and we study at the same school but in different classes. Andrew has got blue eyes and blond hair. He is taller than me. He is cheerful and he is slow to take offence. Andrew doesn’t allow anyone to insult other people. We have a great deal in common, we listen almost to the same music and we regularly play table tennis after school. Andrew is a sociable, kind and modest person. Sometimes he is witty, but his jokes are never wicked. We always find interesting topics to discuss. Very often we visit each other at home. We always can help each other with homework, and we usually play computer and video games together.

Dear Tim,
I was glad to get your letter.I’m sorry I haven’t answered earlier but I was really busy with my school.You asked me about my school.I study at school number seven. My school is a three-storeyed building with a lot of classrooms, where we learn different subjects.Our school has two gymnasiums with all the necessary equipment. We often stay there after classes and play volleyball. Different sports competitions are held there.
And what about your school?How many floors there ?
Anyway, I have to go now because my Mum asked me to help her with the washing up.
Hope to hear from you soon.
