I listened very, very carefully to the world around me to pick up the signals of when trouble was coming. Not that I could stop it. But it made me observant. That was helpful when I became a lawyer, because I knew how to read people's signals. When a witness hesitated, my mind would race to the conclusion that he was trying to hide something. What was it? I'd dissect the story in my brain and nine times out of ten figure out a hole they were trying to avoid.
