How do you tell the difference between when a girl flirts with you and when she is just being nice to you?

I really need help in this area. I never went on dates when I was younger, so I really have no, I guess you would call it, training now in my adult life. It boggles my mind about what a girl is trying to pass on to me, or should I say, is or is not trying to pass on to me. What are some sure fire clues to tell what a women is trying to say with her voice and/or body language and what kind of clues do you women use to convey your ';feelings'; to men? Please help.How do you tell the difference between when a girl flirts with you and when she is just being nice to you?

You can tell if she is flirting with you if she is the one keeping the conversation and if you are she proably is only being nice. If she really likes you she'll keep talking!
