Peter was very joyful boy. Everything made him laugh.
Many times he went out of the class because his giggling.
But this didn't interfere with him to make through the school and university.
And he became a banker (very senior, at the beginning.)
The work was very responsible, everybody behaved very seriously. Once Peter made a joke and they looked at him as he was some kind of slime. That changed his attitude quickly and he became serious too. Very quickly, he forgot how to smile. He became a very sad and unhappy person.
Each year the bank had less and less clients. In another year, it would bankrupt if there won't be any change. Nobody knew how to solve the problem.
This made Peter more gloomy and sadder. He remembered the times when he was happy and could smile. He tried to do it, but didn't succeed. He lost his ability to smile. Though he looked for the smile in his life, he couldn't find it.
One day into the bank came a girl of twelve. She sang. The banker sitting near the door, made her "shhh", but she just smiled to him and made a bow. The man made with his finger no no to the girl and continued to work. The girl showed him the tongue. And then continued to dance as nothing happened.
Peter didn't understand why, but suddenly he began to feel better, sadness retreating, and sunshine entering instead.
It was so strange feeling, that Peter didn't remember how the day finished. He went home by foot.
Near the bank, he passed the large show-window and turned to look. Then he stopped as if struck by the lightning. He was looking into the window and there he saw the answer to his joyful feeling. He saw there the smile.
His smile.
He tried to make serious face and then smile once more. And succeeded. Tried once more. And yes, succeeded once more. He found back his smile.
And then Peter ran back to the bank. Burst into the manager's office and shouted" I know what to do so that the bank well get all his clients back".
Half a year later, you could enter the bank, stand in the long queue and reach the banker who greeted you with such a sincere smile, that you couldn't but smile back.
You didn't think twice if you wanted to continue with this bank or look for some other.
The smile made it obvious choice.
