While reading a book I encountered the sentence I don't understand. Please give me some advice.
Situation: During a class, a student, Ashley Bonny is caught being lackadaisical when she should pay attention. Her teacher, Mrs. Warner stands right next to her.
(The sentence in question is taken from the following passage of the book "The Bonny Pirates" by V B Leghorn)
"Hopefully you were thinking about Shakespeare's prose." Mrs. Warner was being frank and her wrath was quite evident. She had her arms crossed and she was tapping her toe. "Yes, ma'm. It is undeniable. I was absolutely, most definitely thinking about Shakespeare." The classroom erupted in laughter and the boy next to her gave her a jeer. Ashely looked around, blushing that she had blurred out something that made the entire room laugh. A crooked smile crossed her face and she laughed too. Unfortunately, Mrs.Warner wasn't laughing and Ashley could see that she was irate. Ashely had pushed her past her patience pique.
