I noticed something very peculiar the other day, when my ESFj friend sat a meter away from my INTp/INTj friend. She was being her usual bubbly, entertaining self, but he showed no signs of admiration. He fell completely silent and started staring into space, much like I do when I detach myself to focus on absorbing a person's presence. Even weirder, he would move away from my friend, only to move back a little closer. Being in her proximity seemed to make him very self-conscious; it's like he was hesitating between attraction and fear. Which is the same reaction that I have around ESTps.
I have never seen him close himself off like that around anyone else, so it made me wonder. Has anyone else has experienced an initial awkwardness around their duals because they seemed too good? If so, how long did it take for the interactions to become more spontaneous?
