"I never had a dog that showed a human fear of death. Death, to a dog, is the final unavoidable compulsion, the least ineluctable scent on a fearsome trail, but they like to face it alone, going out into the woods, among the leaves, if there are any leaves when their time comes, enduring without sentimental human distraction the Last Loneliness, which they are wise enough to know cannot be shared by anyone."
