A kid goes to the playground to play and he sees an old bully harassing other kids. The kid wonders why the old bully does what he does so he tries to imitate the old bully's behavior and has a little taste of the habit.
For a few months the kid goes on harassing other kids and makes the neighboring kids watch.
Until one day he comes to know an atheist who plays calmly in the corner of the playground with other kids.
The kid watches the atheist and follows him wherever he goes to learn from him but not only does he learn a lot from the atheist, he also learns about himself. He stops his bullying habit and goes to another playground hand in hand with the atheist. They become very good friends and help each other out whenever they can.
One day the kid wanders to another city and finds the old bully he used to know hanging around the bullies in the city but pays no attention to him until he sees the bullies in the city bullying a little girl. The kid stands up and points out the bad habit since he knows what it's like to bully and the impacts it creates. The bullies of the city leaves the little girl alone .
On the other hand the old bully is somehow offended and aggravated by the kid's behavior but sees this as an opportunity to be accepted by the bullies of the city so he tries to gather help from the other bullies to bully the kid but nobody listens to him. He tries a few times but to no avail. Nobody listens to him.
Then the old bully says stupid things about the kid but the kid only shakes his head and sighs.
Moral of the story: Some bullies change, some others just don't want to.
