a friend is someone you can share your secrets. If you
tell him a secret, never will he talks about it with anybody
else. Besides, a friend is always good listener when you
need one. After hear your sad stories, he will say some
words that is nice and warm. Still, your happiness makes
him happily too. What’s more, a good friend is willing to
