     I had never interested in sports,unlike most of my
classmates.After the school they would take part in either
a basketball and a football game,while I stayed inside all
by myself.After some times I came to realize that I had
to change all this when I intended to get along well with
others.So,one weekend,at the great surprise of all my
classmates,I announced that I want to go to the football
game with them.I thought by join my classmates in sports
I would stop feeling lonely,and at the end I might even
come to like sports very much as my classmates did.
