It's almost better most times to not talk in a scene. I think you can actually express a lot more without words.
“I love driving cars, looking at them, cleaning and washing and shining them. I clean 'em inside and outside. I'm very touchy about cars. I don't want anybody leaning on them or closing the door too hard, know what I mean?”
“Democracy... while it lasts is more bloody than either aristocracy or monarchy. Remember, democracy never lasts long. It soon wastes, exhausts, and murders itself. There is never a democracy that did not commit suicide.”
