....I might as well believe in Santa, because Santa sounds more plausible.
I read body language and can read through intuition behind people's intent, tonality of voice, what they are saying and I understand the situation in a more general way. It makes it easier for me to get at the truth of what is going on with someone, however there is no magic in what I do. Its all logical, I just observe the clues people give off and deduce possibilities, which then I can test to get to a probability. Then I can ask or guide them through talk into seeing if what I thought was true or not.
When you see someone is down and then you ask if they are okay, they say that they are okay then turn away and their face looks like someone just died, then you figure out that nobody has really been talking to this girl at this party and all sorts of other pieces come together in your head, then yeah...you'll quickly grasp the whole picture of what is actually going on with them, then you put yourself in that situation and interpret it as if you were her. BINGO.
