"I long ago lost a hound, a bay horse, and a turtle-dove, and am still on their trail. Many are the travelers I have spoken concerning them, describing their tracks and what calls they answered to. I have met one or two who have heard the hound, and the tramp of the horse, and even seen the dove disappear behind a cloud, and they seemed as anxious to recover them as if they had lost them themselves." - Henry David Thoreau, Walden

 When his aunt Louisa asked him in his last weeks if he had made his peace with God, Thoreau responded: "I did not know we had ever quarreled."
