The Gemini Twins Symbol refers to their dual nature. They are a mutable sign which means they are constantly changing.
They are similiar to a chamelion fitting in to whatever situation they find themselves.
If you feel like you don't really know the Gemini in your life this is why.
On the one hand they are outgoing, and social but there is another part that is secretive and afraid of showing who they really are.
They can literally change their minds every hour on the hour. It gets to a point where they don't even know what they think anymore. They have a difficult time making decisions too. For example, they may want to be a 4 different social events one night and then at the last minute decide to stay home and read a book instead.
They are intelligent and extremely talkative. Each sign has a primal desire and Gemini's is communication. They are witty, and quick thinking.
A person born under this sign has a lot going for them. They are well liked, and people generally like being around them.
They are up to date on the latest in the news and their attire is chic. They need a lot of mental stimulation. If things get stagnant they get restless and bored.
The downside to their bubbly, charming, cerebral personalities is they have a tough time stopping all the chatter that goes on inside of them.
They would do well to take up meditation as a way to calm themselves. They have a lot of nervous energy. All of their overthinking can result in insomnia and stomach issues.
They can tend to live their live from the outside meaning they do what they think is right according to the external cues from the world. They would do far better, to get in touch with their real feelings and live their life according to what brings them joy.
