The human brain is a wonderful organ. It starts to work as soon as you are born and doesn't stop until you get up to deliver a speech.
No matter what message you are about to deliver somewhere, whether it is holding out a hand of friendship, or making clear that you disapprove of something, is the fact that the person sitting across the table is a human being, so the goal is to always establish common ground.
I always feel the danger because you might always be subject to an unexpected or emergency event.
