What does Honest to a fault mean?

A person who is honest to a fault will always tell the truth no matter what. This person is sometimes seen as insensitive, but in reality they are simply telling the truth. They know the value in the Words "the truth hurts" but are never malicious in their delivery of the truth. This does not assert that the individual is incapable of being deceptive, but rather states a person will always tell the truth when asked a direct question even if the answer will be difficult for the asker to hear.
