Fitness in Science: Deathly or Demanding

A few days ago a close friend of mine was almost killed in the midst of fitness testing in health class. Better yet, we had a horrible substitute. Lets go into detail: At the beginning of class we first write down our homework, and we checked to see if we had any over spring break. Our sub, Mrs. Hinkie, says "You do! HAHAHAHAHAHA!!!!!!!!!!!!!!!!!" OMG it was the scariest laugh ive ever heard!!! Then, we started to do our fitness testing stations. I, leaving my lab at home, decided to help my close comrade, Shelby, during this lab. We first went to a station where you have to step up and down on a plastic step for two minutes and then record your pulse. There is one hard grippy side down the middle and on the two edges there are smooth plastic pieces. There were two people on the step, one my friend Shelby, and another girl named Megan. Shelby was moving around the side of the step and all of a sudden she slid backwards on the plastic part and twisted her ankle. the sub said in a non-caring voice, "I'll get you a wheelchair." MY friend quickly said no and that she could walk to the nurse because it was nearby. MY sub refused and really didnt even care that she was hurt. How mean!
