I strongly endorse her views that it is Scorpio. Scorpions are known to be bitter, secretive and highly vindictive people. It is the negative sign of Mars and therefore these natives would be full of negative traits that are of planet Mars. Sorry if you are a Scorpio, but they do have their strong points as well.
