My daughter was letting me know how her teeth got dirty. She fell down. That’s how they got dirty. Like other things that get dirty when you fall down – clothes, knees, hands, etc. It was a good time to let her know that typically teeth get dirty by eating something, or then again, by not eating something, but falling is one of the least likely ways our teeth get dirty.
I’ve heard adults do a poor job with the relationship of cause and effect.
The next time you’re evaluating the effects of something, be sure to challenge the cause.
