This is a story of the lake and the three big fish that were in it, one of them intelligent, another half-intelligent, and the third, stupid.
Some fisherman came to the edge of the lake with their nets. The three fish saw them.
The intelligent fish decided at once to leave, to make the long, difficult trip to the ocean. He thought, "I won't consult with these two on this. They will only weaken my resolve, because they love this place so. They call it home. Their ignorance will keep them here."
