They are reading your energy (again, not the weekly horoscope in the paper). People can use all kinds of modalities to read energy, some simple, some incredibly complicated. But the power in all cases comes not from the tool, but from the person using it. Astrology can be used as such a tool, just like runes, dowsing rods, Tarot cards, crystal balls and just plain old sensing the energy through your body. All of these modalities can be utter BS or incredibly effective, depending on who uses them. Each one requires study and practice. And just because someone has studied and practiced something, doesn’t automatically mean they will be good at it.

Of course, I’m not saying every Scorpio man on earth laughs this way, but when I do hear that laugh, it comes from a Scorpio. (It isn’t an evil laugh, if that’s what you were thinking!) There are more Gemini celebrities than any other sign, and more Scorpios choose to become doctors and medical professionals than any other sign. There are endless examples like this and I don’t think they are at all coincidental. After studying the general traits and strengths of the 12 signs, these things make sense. Of course, I would never judge anyone based on their sign, but this knowledge of astrology has become a part of me. When my sister comes home from school ranting, “Ahh, my new lab partner is such a LEO!”, I nod my head because I know exactly what she is talking about. It is things like this that do it for me.
