As a Listener, it Helps to Check if the Person Talking Feels Heard
Have the Talker show This using Hands Apart/Together ...
This visual cue is helpful as it doesn't interfere with the verbal dialogue and it adjusts in-or-out as you listen across time. This is similar to playing "hot-cold" as a child. Moving away (cold!) from great listening - hands together (we're closed off from each other!). Or, moving towards (hot!) great listening - hands apart (we're open to each other!) as if to hug, embrace, or gather up all of the energy in the room.
Just don't assume that you've heard, you have to check it out. Did you understand the content, the wants/needs of the other person, and what he/she is thinking and feeling in the moment?
