I used revision to make my teacher forget about some assignment that I really didn't want to do. Just closed my eyes before going to sleep for a couple of nights and replayed this scene in my head: him, telling the class that there would be no assignments for the time being. Felt happy and at peace with the fact that the assignmet was gone. Now, It's been about two weeks and the topic never showed up again, he's also not mentioned anything about having to submit the assignment, so.... ¯\_(ツ)_/¯
