Stephen KingThe exhilaration was hard to explain. It was a lonely feeling โ a somehow melancholy feeling. He was outside; he passed on the wings of the wind, and none of the people beyond the brightly lighted squares of their windows saw him. They were inside, inside where there was light and warmth. They didn't know he had passed them; only he knew. It was a secret thing.
