Are You a Vacuum Cleaner?

Last week a friend shared her assessment that many people are like vacuum cleaners, merely sucking up everything that is said.  I laughed and said that I've encountered a number of folks who are like lawn sprinklers, freely spewing their opinions without pause.  How awesome it would be if the world was filled with people who are, instead, like interactive video games.   Dialogues are far more interesting than monologues.
