Mrs. Blank (the teacher's name) teaches as if there's a wave chasing after her students, aimed to extinguish their eternal need for knowledge. She never calms down, and sprints from topic to topic, as if the wave is after her, as well. She makes sure each and every student is wearing a life-jacket so they can get back up if they are suddenly drenched with the extinguishing of knowledge. Mrs. Blank's dedication for teaching is like an octopus hurtling along the wave, trying to grab everything before they fall.
Mr. Blank's passion for math is as continuous as a calculator, but one that never runs out of batteries. His buttons may be pushed, but he is as careful to let them come back up as a brand new calculator does. Mr. Blank would never spout 'error', as a calculator does. He will continue to solve the problem, even if the 'dimensions don't match.'
