Years ago a colleague left my firm and went to work for the enemy, so to speak, during a time of great personal challenge and difficulty for me. I was hurt and felt betrayed and unable to trust him. Years later we began working together again. But for me, every subsequent interaction with him occurred within the context of “I can’t trust him.” No matter what he was saying to me, the background commentary in my head ran, “He’s not telling the truth, be careful, watch out, you can’t trust him.”
