If we spoke quietly, our audience would be forced to lower their tones too. And if we stayed quiet despite the noise, the quiet will spread. Because even the Unquiet needs a loud audience to stay loud. Simply because speaking loudly fills one's ears with deafening ring.
So long that one of us is quiet enough, even the loudest and most chaotic will one day run out of voice and find wisdom in hushing up.
What happens then?
For one, we'll hear better. Then respond more efficiently, and get to have more time to do things we actually like. With the people we really like.
For another, it gets easier to look out for ourselves and each other. Like steroids for awareness, for our minds and feelings.
Just from hushing, see?
