Possibly. Try to think of the Vacuu

Possibly. Try to think of the Vacuum as white space in graphic design or advertising. You need white space to give the bit of communication in the middle emphasis. The vacuum is just the idea of nothingness. It's a withdrawl of all expression. No words, little movement or expression, sometimes we step backwards a bit to visually create the feeling of ‘hey, it’s your turn to be on stage and express'.And then when the other person expresses we can come back in and give a warm reward. This creates an almost rhythm to the conversation.So depending on your physical break, which can be either like a vacuum or an expression, you can then Vacuum or reward from there. Does that make sense? I don't know if I'm describing this well
