I was referring to the example in the article of the movie theater incident, but I have a sister who does that with her BF. She is convinced her bF is cheating on her so she tells him things that I know are not true trying to bait him into exposing some untruth he has fed to her. I watched their relationship come completely unraveled because of this behavior.
Personally, I don't think any lie is necessary, but most especially lying to and misleading a child to expose a lie they have told, or a suspected lie.
I don't think adult human beings should knowingly be involved in the practice of deception and manipulation.
