"The earth trembled and a great rift appeared, separating the first man and woman from the rest of the animal kingdom. As the chasm grew deeper and wider, all the other creatures, afraid for their lives, returned to the forest -- except for the dog, who after much consideration, leapt the perilous rift to stay with the humans on the other side. His love for humanity was greater than his bond to other creatures, he explained, and he willingly forfeited his place in paradise to prove it."
