what was the comment of blacksmith what did it signify

Watcher, the blacksmith commented: “Don’t go so fast, Bub, you’ll get to school in plenty of time.”  Yes, Wachter wanted to make fun of Franz because he never saw him going so fast towards school. That day he was late for school. Another meaning of Wachter’s comment may be that he had seen on the bulletin board that there would be no class on French language in the school from the next day. So it was useless for Franz to go to school so fast.
