In one sentence, describe what the following article is about:

If a woman is facing you most of the time, you have her interest. If she is turning her head often to check out the rest of the room, then she is probably looking at other options. A woman's body facing a room full of people is an unconscious way of appearing available, whereas a woman that is facing you, is focused on you. If she is holding her purse or jacket in between you, then she is creating a barrier. She might not even realize that she is doing it, but that doesn't mean you should ignore the implications. It could mean that she is a guarded person, or that she is not quite sure about you yet. Either way, you should know it might be a sign that might not be turned on. If she is creeping in on your personal space, there is a good chance she is doing it intentionally. Just be sure you aren't the one who is actually moving closer. If she has no interest in you, she won't be sharing an embarrassing story from her past. Even if she isn't sharing anything too deep or personal, if she is opening up at all, you're doing something right. If a girl is not into you, she won't have any desire to put her hands on you. If she does, even in a way that is seemingly innocent, it could be a good sign she has some interest. Be sure to touch her back in a similar fashion.

Summary:
Read her body language. Watch the area between your bodies. Listen for secrets. Notice when she touches you.
