Those born with the moon in an Air sign usually respond to situations in a way they think should fit the facts, that is, they act in a way they think others expect them to act, or they imitate the same behavior as others. This gives them the appearance of emotional coolness or non-involvement. Before turning a situation into a physical experience, and before considering the stability or practicality of the thing, or even how they may really feel about it, they tend to do and say what seems appropriate as if it were not really happening to them. In spite of what appears to be their analytical detachment, most of them are loving and loyal in relationships.

As lunar Air sign personalities, those with moon in Gemini can sometimes take their intellectual approach too far. Constant analyzing, rationalization, and acting as though they had already experienced something instead of just thinking or talking about it, can prevent them from ever doing it. They are talkative, mentally alert, and curious about everything. Always looking for some kind of intellectual stimulation, they get bored by repetitive tasks and the same environment day after day. Attracted by intrigue and idle gossip, they pay too much attention to what everyone else is doing. Restless and impatient, they do not always take time to get all the facts before repeating things. As eager to share information as they are to receive it, many of them are talented teachers, writers, and communicators of one sort or another.

Gemini moon personalities are emotionally adaptable. A dual-natured flexibility allows them to say or do one thing with apparent ease, even though what they really think and feel may be quite different. They instinctively understand what others want to hear and what to do to please them, but they don't always know how to make themselves happy. Though quite willing to discuss others, they can be secretive about themselves. Their outer personality may be bright and optimistic but they can harbor inner feelings of loneliness. Moon in Gemini personalities love secrets and solving puzzles. They have highly sensitive nervous systems and, in order to maintain proper physical and mental health, they need to be given varied tasks and opportunities for frequent change of scene or alterations in their daily routine.

Women with Gemini moon are talented with their hands. Though efficient and organized, a certain restlessness makes it difficult for them to remain content with household chores. Men with Gemini moon are quite charming but their temperaments are not particularly suited to sustained passion in themselves or tolerating emotional hysteria in others.
