The first 3 or 4 prompts go well. Then, they start making shit up for making their point. When challenged, they answer "ooops, I made it up", and start again.
I know that this is the way 90% of the people in real life act, but it is quite annoying. Is there any way to curb that? The only good thing is that it admits freely having made things up. Real people start flinging bullshit around or get angry.
