I write at eighty-five for the same reasons that impelled me to write at forty-five; I was born with a passionate desire to communicate, to organize experience, to tell tales that dramatize the adventures which readers might have had. I have been that ancient man who sat by the campfire at night and regaled the hunters with imaginative recitations about their prowess. The job of an apple tree is to bear apples. The job of a storyteller is to tell stories, and I have concentrated on that obligation.
