My most vivid childhood memories are rooted in experiences, not words. I remember what happened far more than I remember what people said. I’m sure that’s true for most of us. You probably don’t remember being told to avoid hot stoves, but I’ll bet you remember the first time you touched one.
That’s why, when I was raising my boys, I knew experiences would impart wisdom and strengthen their character more effectively than lectures would. Plenty of situations on the playground and at school taught them to be kind and to stand for what’s right.
