I agree with Rowanwitch, even if she only knows you a little she still knows stuff about you that can be manipulated. I personally do not believe in this stuff, I once went to one out of curiosity when I was younger and going through a bad time. She said everything I expected and nothing specific. Your friend may be good at what she does but if you believe in this and want a true reading I would see someone you don't know, not even in passing then you can truly judge for yourself.
