And I am guessing you are being deliberately provocative and obtuse.
If you do not enforce positive behavior and proper manners when they are young and semi-controllable, then you perpetuate barbaric and uncivilized behaviour when they become adults.
However if you prefer such antics, I believe there are quite a few available homes in Detroit where you can be subjected to the fruits of such antics from more older kids, usually traveling in packs, 24/7.
Enjoy.
I’m just trying to understand what you want. You don’t approve of how this kid is being raised.
What do you want? Be specific.
