When I feel a girl wants to talk, I'm right most of the time, even though I can't explain why. I think my subconscious picks up on things I consciously can't. Evolution gave us the ability to read subtle body language and intent. Women's signals are quiet during the day—a lingering glance, a pause, proximity to your space. Most guys miss these because they're looking for obvious interest. The girl who lingers near you is showing interest; you just have to recognize the language she's speaking.
