One day, a calf needed to cross a virgin forest in order to return to its pasture. Being an irrational animal, it forged out a tortuous path full of bends, up and down hills.
The next day, a dog came by and used the same path to cross the forest. Next it was a sheep’s turn, the head of a flock which, upon finding the opening, led its companions through it.
Later, men began using the path: they bent down, deviating obstacles, complaining and cursing – and quite rightly so. But they did nothing to create a different route.
