Proverbs in positive psychotherapy. "Justice"

One day a funny puppy was running down the street. Suddenly he saw a boy, walking around. And the boy noticed the puppy. The boy took a sausage out of his pocket & showed it to the puppy. When it joyfully came closer to the boy, he hid a sausage & shouted at the puppy to get out of there. 
The little one felt very sad... not only because someone did bad to him, but also because he himself felt guilty for he trusted a stranger.  
The boy felt quite different - he was very pleased with himself. Being very proud he went away, leaving the puppy alone.  
Suddenly he stood into dirt, slap and fell down. A sausage fell off his pocket. The puppy ran towards it, ate it and ran away. The unhappy boy remained sitting in dirt... 
Justice has been done. The boy's bad deed has been punished.  And the puppy... he swore to not be so trustful with strangers. 

For the kids aged 5-8, I offer a study programme "Magic Zoo" that will help to develop important qualities and capacities.
