Agree with you 100%. As young’uns my kids got tapped on the butt when they did something wrong. As they got older, they were always well behaved. Could got to any fine restaurant with them. Never had a checkout meltdown like the brats of today.
Spare the rod - spoil the child
The best behaved kids at my church, and the family sits behind my wife and me so we know, have parents who are both USMC. No coincidence and Semper Fi.
