I'm a Gemini to the bone, born on june 15th. It's quite complicated to express the way we see the world; good thing we're efficient communications.
I communicate openly and I always mean what I say, because I usually have time to think twice before speaking. I can find things to talk about with virtually anyone, even if I don't have a clue about cloning sheep, growing peach trees and so on (you get the ideea),
My best friends are there for me, but, sadly, I don't feel any emotional attachment to them. I analize and look into every move they make, before making my decision. I often find myself lost in my own thoughts apparently without any reason, but I do a lot of thinking. I never ever turn my back on them when they need me, and they come to me for advice when they feel it's appropriate, but I never ask them to do anything for me; I only work with other geminis (and they're so rare! lucky my big brother is one).
The only person I feel I can truly trust is my boyfriend (who, incredibly, is a Cancer). I really do care about him and I know he shares my feelings.
Maybe my saggi arising is to blame for my philosophic side, but I do know how to have fun and enjoy life at the fullest and adapting to almost any given situation.
About the pisces guy issue: I once dated a pisces, and believe me, it's a challenge.
He's very, very complicated to understand, but also cristal clear. That's because he, like us, has a dual nature of some sort.
The guy I dated for a while was a writer; a small one, but still. They've got great sense of humor, that I can guarantee. If the two of us started cracking jokes, our friends would almost suffocate. But under that sense of humor and apparent superficiality, lies a bunch of mixed feelings. You can't ask a pisces guy to tell you his agenda for tomorrow; the guy I dated never planned anything.
He was very emotional and showed his feelings in a very unique way, but you can't ever be sure.
I hope I helped :).
