Sitting anxiously in class trying to finish your test, you cannot help but hear the obnoxious kid next to you. As he throws down his pencil louder than ever and takes a huge sigh while scooching out his chair so it makes a squeaky noise on the floor, you can’t think of the formulas for the equations you’re working on or even coherently read the next word problem. Looking at the clock after you finish listening and rolling your eyes at this kid, you realize only five minutes remain in class.
