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.
After so much use, in the end, the path became a trail along which poor animals toiled under heavy loads, being forced to go three hours to cover a distance which would normally take thirty minutes.
Many years passed and the trail became the main road of a village, and later the main avenue of a town. Everyone complained about the traffic, because the route it took was the worst possible one.
Meanwhile, the old and wise forest laughed, at seeing how people tend to blindly follow the way already open, without ever asking whether it really is the best choice.
