we shout when we don't feel heard. The louder one voice gets, the louder the responder must become to be heard; and the snowball of getting louder, the justification of not being heard lets one's voice continue to get louder in an effort to speak over the "unheardness" of the other. Once the snowball effect begins, stopping it becomes a bigger challenge then those feeling unheard can practice, while still trying with all their might to yell louder, forcing the other to become a listener and to hear. A peaceful heart, the practice of listening wholly is the only way to stop the yelling. One committed listener can quiet the yelling, if they so choose.
