Communication breakdown occurs everywhere. Between teacher and student, business partners, romantic partners, etc. It’s important to prevent communication breakdown to maintain social and business related relationships, prevent misunderstandings, and be able to effectively share information.
For example, two friends talk in a cafe. Because of the relatively noisy background, the black friend misunderstands his companions explanation. He goes into an enraged state and leaves his friend with 17 broken bones, a ruptured kidney, and exactly 3 limbs left attached. All this because he heard him say a certain inappropriate word in which I will be punished severely if I do say it here instead of Niagara (falls). As such, if the friend was only given time to clarify what he had said, one would be charged with assault and attempt of murder, and one wouldn’t be a quadriplegic for the rest of his life.
