Forgot My Math Exam Was Today

So, yeah, I totally forgot about today's math exam until I walked into class and saw everyone scribbling away. It’s like my brain has a personal vendetta against remembering important things. I tried to act cool, pretending I was running late because of traffic or something equally plausible. But then the professor looked at me with those eyes that say 'you know exactly what you did.' I swear if math wasn’t so hard for me already, this would be the final straw. Oh well, better luck next time, assuming I remember there is a next time.
