The Concept of Lieing

In some kind of dream, I was trying to explain to someone about what it was to tell a lie. The other person was confused at first but then I felt a sensation of excitement and she said she thought she understood. She said, "So it's like when someone says they are going to do something and then they don't do it." I said no, that's not exactly right but it seemed that was as close as she could come to understanding. I had the sense that we were communicating telepathically and because she was telepathic, she was unable to fully conceptualize the idea of lieing. It was too alien to her.
