Even when I'm not scheduled to run, I sometimes find myself in situations that demand I hop to it.
Today, I was in my noon class -- on the fourth floor of the library -- and as I was handing out their quizzes, I realized I was two copies short. I have never under-copied before, but even super-hereos make mistakes, so I assured them they could sit still and I would be back in a jiffy, quizzes in hand.
The original copy of the quiz was back in my office, in another building. I knew right away my shoes would be an issue, so I slipped them off and, shoes in hand, went sprinting in my bare feet. Down the four flights of stairs, across campus, into my office, I quick made two copies and then jogged back across campus and up the four flights of stairs. Keep in mind, this is Florida, it was 1:00 in the afternoon; currently, it is 90 degrees outside. So, I burst back through the classroom door (shoes still in hand), sweating and a little out of breath from the stairs, and handed them their quizzes (they had generously offered not to take the quiz, but I didn't want to inconvienence them).
They finished, turned them in, and had plenty of time, but I was sweating and flushed from the unexpected exertion (nothing like having sweat roll down your back in a dress shirt). I guess the lesson learned is that I need to quadruple check my copies before heading to class so I don't have to run a 100 yard dash in the middle of the day. I'm just glad I didn't bump into another professor mid-run.
