A microphone makes one fact impossible to ignore: somebody else is lending you their time.
On radio, every second has weight. Too many words and the listener leaves; too few and the thought never arrives. The task is not to fill silence. It is to know which silence allows meaning to form.
That lesson survived the studio. Meetings, advocacy and organizing also depend on attention: hearing what a person actually said before translating it into a category or procedure.
To listen is not to wait for your turn. It is to let another person alter the next sentence.
