From my experience I see that we are all born a clean slate, an empty page. "Caregivers" and others are handed a crayon. Some start off a little wobbly but through experience improve their writing on this page, sometimes an eraser is required but remnants of the writing remain. Others just scribble on the page creating chaos. Still others just crush and crumple the page and discard it.
It is our role as adults, whether parents, family or not to write with our very best hand writing on our precious pages, the next generation(s).
