I'm happy because I have friends. Because I have precious friends, I can go on forward.
If you have friends, you feel twice as happy when something nice happens. The more the friends you have, the double the fun when something happy happens. If you have friends you can easily forget disagreeable things. The smiling face of your friend is a most necessary treasure to live your life joyfully. And you as their friend, your smiling face is a treasure that is necessary to their life as well.
