I've never thought any one of the same age of me could be more special than me until Mary came into my life.She is an optimistic girl always with a sweet smile on her face.She has a pleasant personality and always willing to help others.There is no wonder that she became my best friend since we have so much in common.For example,both of us are big fans of sports and books.We often go to the playground to play badminton together or read books under the old palm tree of our school.When we are with each other,we have endless topics to talk about.I wish our friendship would last forever.
