The irony of passion for poetry
It's ironic that Jack rejected Miss Stretchberry's writing prompts at first, but went on to write and become passionate about poetry. He was initially opposed to writing poetry, believing that he had nothing to say and that the poems made no sense. Despite his reservations, Jack eventually accepted Miss Stretchberry's writing prompts and began to find his voice, eventually becoming passionate about poetry.
Irony of plagiarism
It's ironic that Jack is afraid Mr. Walter Dean Myers will be upset because he plagiarized, but Myers is honored. Jack was so concerned about plagiarism that he asked Miss Stretchberry not to type up and display his poem inspired by Myers. When Myers came to visit, he was touched that Jack had been inspired by his words and had written a poem in response to his own. In the end, Myers was grateful and honored, rather than angry, as Jack predicted.
The irony of Jack’s poems
It's ironic that Jack thinks his poems are bad while his classmates think they're fantastic. Even though his peers like and appreciate his work, Jack is constantly doubting his writing and talent. Jack's self-doubt and lack of confidence in his writing are what drive him to conceal his identity and cover up his work. He is so self-conscious that he is unable to recognize his talent or the caliber of his work. His classmates, on the other hand, recognize and appreciate his talent and work, and can provide him with the encouragement and praise he requires to overcome his doubts and insecurities.
The irony of the visit
The irony in this situation is that Jack assumed Myers would never respond, but Myers agreed to visit his class. Jack had been hesitant to write to him because he was convinced Myers would never respond. But when he did, Jack was taken aback and overjoyed. Not only did Myers respond, but he also agreed to come to the class and even had a friend in town to accompany him. This unexpected turn of events pleased Jack and his classmates and resulted in a successful visit.
