Observe her body language.
Male and female body language isn’t entirely different. For example, if you see her tapping her fingers or looking around the room, she is probably uninterested. If she runs her hands through her hair, plays with her earlobes, or bites her lips – she is probably into you. Smiling isn’t always a good thing, either. If she shows her teeth when she smiles and looks at you, it is a good sign. However, if she doesn’t show her teeth and looks away after smiling, she is not interested.
