A third position is the observation of what is happening between "One" and the "Other".
One way to learn more and develop a deep understanding of communication is to change your point of view.
People with good communicative abilities use multiple perception positions, which are different perspectives.
Sitting at the party, people are laughing at me, I walk away. Observing the others with detachment, in third position it reveals everyone's boredom. I am not offended and turn my attention towards something else.
