There's really no way to twist your comments especially when every poster came to the same conclusion. There's not a generalized comment either. You brought your kids into it. I'm glad you have a strong relationship (or at least how you describe it) but that's just your response to my observation. Your first inclination is to talk about grades. It doesn't even make sense with the rest of your comment to talk about no phones, tv, etc when the premise of your viewpoint was your desire to physically mete out punishment wistfully and understanding boundaries and respect. But even if you were forms of punishment like that also aren't indications connected to academic success. If your point is about boundaries and respect you would want to speak towards those attributes. It's not just you, it's this one thing that somehow academic success is the blanket of all blanket "my kid turned out well". There's more to a person than their high school grades.
You can stand by your convictions, research says otherwise.
