Complete answer:
The narrative is told by Franz, a little French child. Franz is prone to procrastination. Franz likes playing despite his laziness and is a sensitive guy. Franz despises M. Hamel, his French instructor, and has no desire to learn the language.

In these two districts, the French language was no longer taught. The French instructors were informed that they would be required to go. M. Hamel was unable to return to his former school as a result. Regardless, he gave the last speech that was full of dedication and honesty. M. Hamel was dreaded by one of his students. This student anticipated being penalised when he came to school that day. He did, however, discover that this was going to be his last lesson. He instantly grasped the importance of the subject. This storey shows how individuals feel when they can't communicate in their own tongue.

The instructor, M. Hamel, announced to the students that it was their last French class in a sombre and kind tone. Only German will be taught in Alsace and Lorraine schools from now on. The new master would arrive the next day. He urged them to pay close attention because it was their last French lesson. The narrator was astonished and surprised by the teacher's nice gesture and soothing remarks.

Note: The narrative emphasises the importance of keeping one's identity and culture rather than allowing it to fade away or be assumed. It emphasises the importance of keeping one's original tongue in order to preserve one's identity. It emphasises the importance of maintaining one's native language's tradition and history.
