A professional liar is someone who is able to make up a story and tell it in such a way with false supporting details to make listeners belive its true. A good listener however will be able to pick up that some part of that story does not correspond with other parts of it. However when these types of liars are caught in the act they rarely ever have support to back up there story. Most of these types of liars are very insecure about themselves so they make up lies to convince themselves that they are something when in reallity they are nothing. Liars like this never admit they are lying because that is there way of life.
"sentence form" Nadia is a professional liar that talks all day but cant back nothin up.
2. a politician
to get elected, politicians must make all kinds of grandiose, but vague promises, which they have no ability to keep, and no intention of even trying. Once in office, they must continue to spin convincing lies about how they are keeping all their promises and making everybody's life better, while, in reality, they are robbing you blind and screwing the country over big time. Politicians are therefore professional liars.
Bush, Obama and all those other professional liars should be hanged from all the lampposts on Capitol Hill
