Wow really? That's too bad. Actually, I was really good friends with a compulsive liar. He wasn't a sociopath though. Lying was his only vice I guess but he just couldn't stop. It was sad but after awhile you just nod and smile. The lies usually involved himself trying to make himself appear better or impress otherwise he wouldn't hurt a fly... He wasn't malicious. He didn't seem to be someone that had no conscience and would do terrible things or hurt people.
