There is no “building attraction” or any other strategy.
You add her on Facebook, as you are off to continue your night. An hour or so later you remember to message them and they join your group. They want to too, because you’re the rare breed of guy that’s not in pac man mode, and they feel safe and warm and attracted.
You laugh together, flirt, hug, and kiss. You have a GREAT VIBE between you two. She’s that kind of girl you want to see again. And you do. All in all, a fantastic carefree night of fun and enjoyment and the girl you met was just a nice perk.
You felt whole and autonomous, and totally content with or without her. This way it was so effortless that you eventually did not have to perform and do anything to “get” her.
This is THE SOCIAL HEARTISTRY way.
