"Oh, so you deceived."
"No, no. I didn't intend to deceive. I just didn't mention anything that might have disturbed the other person."
"But you were aware that the omission would cause the other person to believe something that you knew was not true."
"Well, yeah. But I didn't lie."
"How do you think that person will feel if the news of your creative editing is revealed."
"I don't know."
"I'm not sure if you're being honest about that. How would you feel?"
