Yes, they are really great! We're talking about Aries and Sagittarius...
People born in this sign are considered to be excellent people. They are also very jealous. By the way, Sagittarius is the most sincere sign in the horoscope. The only flaw is that they may sometimes exaggerate when it comes to their adventures. But they don't do that to lie, but to entertain their public. Also, what many consider being 'ugly truth', Sagittarius say it to your face.
Aries always says what he means, but mostly because he is impulsive. They are very energetic, but they don't waste their energy on lying.
Brutally and sincerely- that is how Aries treats others. Sometimes their honesty hurts other people, sometimes they regret their honest words, but they will not give up on honesty because it is their other 'self'.
