Violent agreement
A truly and thoroughly robust disagreement is an energetic experience.
When all parties come together in good faith with different perspectives, it takes great effort to explore.
When minds are engaged, heart rates go up and the body can start experiencing threat responses. Sometimes when we have already reached agreement we continue going on the pure energy of the interaction.
I check by asking "are we in violent agreement?". If that is met with laughter, our conversation is concluded.
