In a conversation, one listens mainly to correct, approve or contradict. Part of our attention remains busy defending our place. One of the exercises in the book is to observe this reflex, leaving more space for the other's words.
Accepting a point of view does not oblige one to share it or abandon its limits. The challenge is to see the tension that sometimes produces the need to cut each exchange. Difference can exist without becoming, at every moment, a fight.
