Libra: Being a mutable air sign makes Libra the most diplomatic and less ruffled of the zodiac. They are very polite and can be quite charming, so others seeing their angry outbursts is usually unlikely unless they're mad enough (usually, like I've stated before, the entire world can't be classified only by it's sun sign). Libra's like to keep their cool and can continue to be quite calm when even the others have reached a point of anger. They like to be above uncontrolled bursts of emotions. However, behind the curtain the Libra has one of the most unmatched anger among the zodiac. But really, how would the rest of us know when Libra keep themselves so composed?
