Interesting article

Tonight while hanging out with some friends, we began discussing what constitutes a pathological liar.

I googled it:

http://wiki.answers.com/Q/How_can_you_tell_if_someone_is_a_pathological_liar

That article led me to a few on narcissistic personality disorder. This seems to be the underlying cause of Pathological Lying.

The things you learn at trivia.

Good reading for sure. Enjoy.
