" What happened to you as a child, particularly something bad, changed you, absolutely and completely. It was like part of your brain became closed off and refused to mature any further. As an adult you were powerless to fight against it. It was simply who you were until the day you died. There was no “therapy” that could cure it. That wall was built and nothing could tear it down. "

― David Baldacci , The Hit (Will Robie, #2)
