Native Americans would say that [the sight of a fox killed in a trap] was the moment when my fate was sealed. They say that you sign nature's unwritten contract to work with animals at a very young age as a result of some experience, either good or bad, that happens in early childhood. Looking back, there is no doubt that the shock of seeing that magnificent young fox-my friend-hanging from that tree left me with a feeling of revulsion for my own kind and a desire to distance myself from the human race.
