“He'd make very interesting noises. His laugh was explosive and uninhibited. It was the kind of laugh that made you feel good for making him laugh. His sneezes were booming. And sometimes he'd talk to animals in their native tongue. The times we'd see dolphins, he'd greet them in a reasonable approximation of dolphin speak. They'd often answer him. I have no idea what was said. But my favorite sound of his was the sound he'd make upon discovering something interesting and new, some idea or possibility that impressed him or opened up a fresh way of looking at things. It was a kind of "aaah." One of my proudest moments: We were watching my first Star Trek episode, "Attached," and within minutes he'd made the sound, turning to me with a beaming smile and saying, "That's really good." And this continued for the entire show. The completeness of how much he loved what I'd done, that genuine sense of enjoyment stays with me, a sense of respect and approval I treasure like nothing else. ”
