3. They keep lying even if they’re caught

This is surely one of the things that could make you angry. You know that someone is lying, and you know the truth for sure. You might tell a pathological liar that you know what actually happened, but they won’t agree with you and will go further with their story.

So, they don’t have a problem with lying, even if they’re caught, because that’s their way of life and they can’t help it.

It’s indeed annoying to be close to someone who does these things because you can never know what their true intentions and thoughts are. If that’s the case with someone you love, it might be better to advise them to go to therapy to try and solve this issue.
