When I first met Bill* at a Los Angeles coffee shop I frequent, I thought he was homeless. He was wearing a rumpled, food-stained shirt, and his hair was a matted-down tumbleweed that hadn’t been cut or washed in years. I was surprised to learn that this shuffling, dishevelled figure was a successful illustrator for a popular TV show. His downcast mood seemed to have changed one afternoon when I saw him glide past the palm trees in the coffee shop’s courtyard.
