The key word for Gemini is versatility. They are expressive and bright and they represent two sides of their personality. You can never know in advance which side you are to face if you confront them. On one hand they love flirting, they are communicative and ready for any fun, on the other hand they tend to be serious, anxious or even indecisive. Both parts of Gemini are able to adjust to life situations, which is pleasant for their surroundings. If Gemini are present, you can be sure that you will never get bored.
