Fritz had to stop himself from interrupting when Karl spoke about the difficulty of working. Stories are just as hard as clocks to put together, and they can go wrong just as easily--as we shall soon see with Fritz's own story in a page or two. Still, Fritz was an optimist, and Karl was a pessimist, and that makes all the difference in the world.
