"...and you have nothing to say about it? What are you thinking?"
"That I don't know who to believe, you or Nguyen."
"You believe the one you trust," Cohen said.
"And why the hell should I trust you?"
He shrugged. "There's no should about it. You either do or you don't. You have a lot to learn about life if you think people have to earn your trust."
"You can't talk your way around this one, Cohen."
He shook his head and went on as if she hadn't spoken. "You don't trust people because they're a sure bet or even a good risk. You trust them because the risk that you'll lose them is worse than the risk that they'll hurt you. That took me a few centuries to learn, Catherine, but I did learn it. And you'd better catch on faster than I did. The way things are going right now, I don't think you have a century to spare."
