Thanks bro. You're right, most adults don't see this. Including my missus!
Kids are a total joy and all they want to do is learn and have fun. And it is only the adults who enforce rules which cut them off from this. If I was in charge there would be no rules other than those required to let them know what is safe and what is not.
Have fun with your nephews!
I totally agree with you man, you're missus will shift her paradigm if you keep it up for sure... haha I would totally do the same let their adventures run wild. Thanks bro will do, same to you and your son!
