As children, we learn new words at an astonishing clip. They don't beat around the bush. Their words are personal and powerful. They are filled with will and intent. They are filled with passion and purpose.
Children trust the power of words.
My guess is that for most of us school is where this sorting starts to happen. In school it usually means clear, orderly thinking. Neat enough grammar. Lots of orderly facts. It is a rare teacher who takes the time and care to praise the kind of writing that doesn't fit into an academic paradigm.
