MEN WHO BELIEVE that they are accomplishing something by speaking speak in a different way from men who believe that speaking is a waste of time. Bobby Shaftoe has learned most of his practical knowledge--how to fix a car, butcher a deer, throw a spiral, talk to a lady, kill a Nip--from the latter type of man. For them, trying to do anything by talking is like trying to pound in a nail with a screwdriver. Sometimes you can even see the desperation spread over such a man's face as he listens to himself speak. Men of the other type--the ones who use speech as a tool of their work, who are confident and fluent--aren't necessarily more intelligent, or even more educated. It took Shaftoe a long time to figure that out.
