One signal in isolation does not tell you much. A smile is just a smile. Eye contact can be coincidence. But when you start counting two, three, four, five of
these signals appearing in the same interaction? That is not coincidence. That is communication.
Tune in, as Charmaine says. Watch what she does with her body, not just what she says with her words. If the signals are there, take the next step confidently. If they are clearly absent, do yourself a favor: wish her a good evening and move on. Every moment you spend chasing someone who is not showing these signals is a moment you are not available for someone who will.
The goal is not to decode women. The goal is to stop second-guessing what is already in front of you. Her body is already telling you the answer. Start listening.
