My parents while Christian weren't church goers.
When I fucked up I got an ass whipping my parents never grounded me or took away privileges.
It was simple and effective.
Why do you think we have so many entitled little shits these days? I'll tell you,kids today know there will be no consequences for their actions or if there are they're so mild the kids just laugh.
When I was in school you got swatts if you fucked up,and when you got home you got em again. Your parents didnt take their child's side they were on the side of the adults. After parents started taking the side of their kids is when society broke down and we ended up with what we have today...a bunch of worthless mouthy punks with zero respect for their elders.
