"People are generally amazed that I would take an interest in any form that would require me to stop talking for three hours"

Henry A. Kissinger's quote suggests that he is a person who enjoys talking and talking. He is amazed that people are amazed that he would take an interest in any activity that would need him to be quiet for three hours. This could be interpreted as a sign of humbleness, as he knows his own tendency to talk and wants to put it aside in order to take part in activities that need silence. It could also be interpreted as an indication of respect for the activity, as he wants to put aside his own choices in order to totally participate in the activity. This quote reveals that Kissinger is a person who wants to put aside his own preferences in order to engage in activities that need silence and regard.
