OT:
Grandma alwees sed, "Ya kin leed a horse ta water but ya kant make em drink."
So no matter if you talk yourself blue in the face, no matter what you say, people are still going to do what they want to do. Worse, if they do what you tell them to do and it's wrong they hate you forever. Better let people make their own mistakes. Do their own DD. Self appointed saviors run the risk of getting crucified on the cross of negative public opinion.
JMHO
It's what you learn after you know it all that counts
Most of the shadows in life are caused by standing in our own light.
Don't be afraid of shadows, it means light is near by.
