What kind of person is one that is so good at lying, even when you know they are lying, that you get drawn in and even believe them, even tho you know what they are saying is a flat out lie.....

Not that I'm that gullable that I believe what anyone tells me.. Never met anyone like this before...SO just wondering what kind of person is this? One that is soo good at lying, that I guess they might even believe their own lies? And you don't come to your senses until they leave your presence.

ANYone ever meet anyone like that? AND what type of personality is this?

Just curious
