General behavior:
Gemini (the twins) is a very complex and confusing sign. To some people you can seem like a wonderful friend, while to others you will seem two-faced and sneaky. You will act like a child for most of your life. That includes both the good and bad characteristics of children. You are happy and energetic when things go right for you. However, when things go wrong, you can be passive-aggressive and very mean. You find decisions hard to make, since you can never stay with the one that you originally choose. You tend to fight loosing battles for something that you call a "moral" cause (even though you know it isn't). One quality (you decide whether it's good or bad) you have is the ability to lie and appear that you are telling the complete truth. You prefer to use someone else's solution to a problem than thinking of your own. Many of Gemini's poorer traits are due to your lack of self-esteem. It is very tough to get your attention. You will be thinking about many things at a time and you can't concentrate on any particular thing at one time. You may be praising somebody but at the same time you will be thinking against him(her). But the most intelligent people on the earth are Geminians.

I so LOVE the last sentence. It is so VERY true =)=)
