Beverly Cleary once received a fan letter from a dying man. He was 56 years old, retired and “very weak,” he wrote. “That’s why I have such sloppy handwriting.” But the penmanship wasn’t so much sloppy as childish, Cleary recalls. “And then the last line was, ‘P.S. That is all a lie.’” She wrote back and told the boy he had a fantastic imagination.
