I think a good friend is like a mirror.
My best friend is such a person.I'm quieter and more serious than most kids.That's why I like reading books and I study harder in class.My best friend is quiet,too.So we enjoy studying together.But we are not in the same class.So we don't often meet.She is popular in her class.She is taller and thinner than me.My eyes are bigger than her.
We both like sports,but she plays football better than me.However,she often helps to bring out the best in me.She is good at math,but I'm not.My Chinese grade is better than her.Friends are like books一一you don't need a lot of them as long as they're good.
