In this short story, the main character really likes this girl in his class, and he tries to impress and be friends with her by going to the same French class as her.
He is constantly thinking about the girl, Teresa, and when the teacher asked him to say a proper noun, he said Teresa. He constantly tries to impress her and during French class, he tries to impress Teresa by saying “French”, even though it was complete gibberish. At the end of the class Teresa was impressed and started to talk to him and asked if he wanted to study with her. The boy was obviously excited and said yes, but this was still at the end of French class. Even though the teacher knew that the boy was faking it, the teacher didn’t interfere, having sympathy for him.
The moral of this story is that we shouldn’t fake who we are, if we do, in the end it would be us that will get a hard hit. Fake it until you make it.
