Input: Text: i work as a ta in my university, teaching math. today i had to practice a certain concept they'd been taught by the instructor during the lecture earlier this week, a concept that is not easy to grasp. i decided to try and elucidate it using an original example i'd come up with, but in retrospect the example was so needlessly convoluted that it not only did not make matters any clearer, but even those bright students who thought they'd got it from the lecture, left my class feeling confused and angry with me. a couple of them walked out on me mid explanation in a demonstrating manner before the class was over and i heard snickers behind my back. how can i make things right with them? how can i restore their confidence in me?

edit: vocab: "demostrably" ->"in a demonstrating manner"

TIFU by teaching a simple concept in an extraordinarily convoluted way
