Sagittarius's relationship with life is built on curiosity and optimism. A new city, a new idea, a foreign language, anything it doesn't yet know feels like a calling. Even in a difficult situation it usually finds a bright side, and it carries that hope to the people around it. Its laughter comes easily and its conversation ranges widely; it puts any room at ease.
