Libras are an air sign known for their sociability. They are rarely alone and care deeply about justice and fairness. They put a lot of emphasis on what other people think about them and are compassionate and charming. Glinda, the good witch, is a perfect example of a Libra. She's widely loved, sociable, and gentle. She is rarely alone, always surrounded by munchkins, and she takes it upon herself to be a beacon of good in her community.
