Writing is weird.
You make these scratches on paper and they mean something to you. Maybe something very profound. Maybe a shopping list.
But to some, they would be just symbols, squiggles. Nothing. Meaningless.
When I write down my thoughts, they become much clearer to me. I can understand better what I am actually thinking and feeling when I write it all down.
People would argue much less if they had to stop and put their thoughts down, coherently, on paper before they opened their mouths.
