Do People Listen When You Speak and When You Don't?

I found this quote from the December 13, 2009 edition of the Dallas Morning News interesting

"Henry was incapable of overstatement, so when he spoke, we all listened. When he didn't speak, we listened." -Senior Rabbi David Stern of Temple Emanu-El on the life of Dallas real estate icon Henry S. Miller Jr. (dallasnews.com, Tuesday).
