I don't really believe in palm readers and crystal balls and tarot cards, but I respond to the need for them.
I find that when I play reality-based characters, it is only as fun for me if I have a lot of time to do research. If I don't it just isn't exciting but if I do, it can be fun because I can learn about that person and the world that they live in and I can become somebody else.
It is of no help to us that there is an absolute truth of the matter of things because unfortunately, none of us are in a position to say definitively what that is - although we all think that we are.
