How did Franz‟s feelings towards schoolwork and schoolbooks suddenly change?

Dear Student,
Franz was shocked when M. Hamel told the students about the order from Berlin and that it was their last French lesson. He forgot about his teacher’s ruler and crankiness. He developed a fondness for M. Hamel at the troubling idea of being separated from him forever. He understood the pain and agony his teacher was undergoing. And, he became more sympathetic towards his teacher.

His school too, now, carried a different meaning. His books and lessons seemed old friends whom he couldn’t give up. He realised with pain how much French meant to him and regretted not being attentive in his classes earlier. Suddenly, he felt that the ‘difficult concepts’ had never actually been difficult.
