This may sound a little dumb, but based on what the website's law of least effort and slow walking, how do u approach a girl who is walking at lightning pace while seeming to have put in zero effort?
Wait for her to stop (at an intersection, for example) or just jog after her. You can apply effortlessness to the rest of your interaction with her following the opener. You can also resume slow, sexy walking after you're done with her.
