The idiom “When pigs fly” is used to express that something will never happen. In a classroom scenario, a teacher asked each student to share their aspirations for the future. One student bravely expressed his desire to become a teacher, just like his own teacher. The teacher felt a surge of pride upon hearing this response. Aware of the student’s mischievous behavior and lack of dedication to his studies, the teacher still wanted to encourage him and said, “Work hard, and you will achieve your dream.” However, a friend who witnessed this exchange expressed disbelief, remarking that pigs would fly before the student could become a teacher. Surprisingly, as time passed, the student developed good habits and diligently worked towards his goal, ultimately becoming the best teacher in the entire town. This story defied expectations, proving that with determination and growth, even seemingly impossible dreams can come true.
