Someone gasped, breathing quickly, then sneezed with a loud 'CHOO!'
"Detention," Professor Umbridge said sweetly.
"Professor?" Anthony Goldstein asked, putting his hand up.
"Mr. Goldstein, I hope I do not have to explain to another prefect how important it is to have proper manners in class?" Professor Umbridge asked. "It should be easy for you to wait until I call on you. I thought prefects were supposed to be well behaved."
Anthony kept his hand up, and Professor Umbridge let him wait like that for almost eight minutes before finally calling on him.
"Professor, Mike only sneezed," Anthony pointed out. "You can't give someone a detention for sneezing."
"Mr. Goldstein, are you the teacher in this classroom?" she asked.
"No, Professor," Anthony replied.
"That is correct," Professor Umbridge told him. "That is because I am the teacher, and I can give detentions. If you try to tell me what I can and cannot do in class then you will be getting a detention as well."
Nobody said anything for the rest of class, but Harry could guess what they were thinking.
He sort of wondered if you could give a teacher detention. And whether he should use his magic book cover to make it look like he was reading Defensive Magical Theory while actually reading something more worthwhile (such as almost anything).
