Open the blinds because that man...he's at your front door...."WHAT DO YOU DO?"
My son looks at his father, anger and defiance in his eyes. He balls up his tiny fists and looks his father square in the eyes, without hesitation he says: "I DEFEND MY FAMILY DAD!! I'M NOT GONNA LET HIM HURT MOMMY OR MY SISTER, DAD!!! I'M GONNA FIGHT HIM, DAD, I'M GONNA FIGHT HIM!!!!!"
Congratulations, you've got yourself a good little soldier there. Make sure he gets a gun as soon as he's legal.
