A car hit me on my bike and I ended up bloodied and bruised , but instead of going to doctor , I dragged my ass pulling my broken bike behind me to class to try to make it to the test . I show up with my bloodied knuckles and torn clothes about 15 mins before class ended and ask the professor if I could take the test after I see a doctor . Says no , rules are rules , take it now or get a zero . Screw the professor . Screw policies . Common sense needs to prevail under certain circumstances .
