John who had been busy cleaning the bathroom floor, went up to the professor "I've finished cleaning it" His hand were now feeling very numb and he was feeling sick from all the cleaning it had taken to clean the bathroom, the water was pitch black now. He wondered how many nightmares he would have about cleaning when the detention was final over. "I hope you like it" He felt like crying and he knew that there was a lot more for him to do to make up for what he did in the Professor's office. He waited for the Professor to see the bathroom and give his next instructions.
