Yui and Yob were two serpents which forever lived in conflict.
Yui always wanted to make Yob feel bad, so he said to him in their adolescence period:
“Yob, you are nothing but a rat because I’ve said so.”
Yob, however, never believed in Yui, and always doubted everything he said, so he did not think he was a rat, and so Yui was unsuccessful in his attempts.
But, he was forever reminded of this one phrase Yui kept telling him.
Time came, they were adults now Yui came to show Yob love and kindness. They both came to love each other and believe in each other fully.
They went back into the school yard from years back, it was rainy that day.
“Doubting is the biggest sin... doubting everything is recklessness. if you doubt you are not being cautious and secure - you are squandering security in itself. once you’ve doubted everyone - why of course, no person is worthy of your trust! and now what shall you do? rely on yourself? Well, good luck with that! worse than hurting yourself, however, you hurt more than who you doubt. all human actions are impressionable - doubt the person and the person begins to doubt himself. you see him doubt himself and you doubt yourself! Suddenly everyone doubts and everything and they all fall into a deep chasm! Trust is the foundation for any type of progress! and the bigger the trust, the bigger the progress!
“Ah," Yui said, "you are so right... then is there anything in the world more pure than the
absolute truthfulness of two friends?
Yob?”
Suddenly Yui noticed that Yob was gone completely. He looked at the floor, a small rat squirming in the cold. It squirmed out into the horizon. Yui was left alone for the rest of his life.
Yob said - "Yui, what did you say I was once?"
Yui - "oh, that you were nothing but a rat?"
Once he did, Yob turned to a rat forever.
