In the poem, the boy's face turning red after being caught cheating in the exam is compared to a fire engine, symbolizing extreme embarrassment and humiliation
The simile "felt like a war criminal" suggests that the scolding from the principal was as severe as the punishments a war criminal receives, making the boy feel deeply ashamed
The boy's nervousness and stress during the exam are depicted through the simile of sweat shooting out from his forehead like a sprinkler watering a lawn
Answers in the exam are personified as playing hide and seek with the boy, indicating the effort he had to put in to find them, similar to searching for hidden objects in the game
The moral of the story in the poem emphasizes the importance of studying textbooks to perform better in school
