" In high school, I could recognize extremes of emotion. I knew enough to run if a guy came yelling and screaming at me with a baseball bat. But a girl with a subtle expression on her face … was she smiling at me? Laughing? Quizzical and curious? I had no idea. That led to a lot of awkward interactions and years of loneliness. "
