Gimme my money, Nig*a!!!

Yes ladies and gents, that's right. I said it. No actually it was said by a 2 year old black boy, to his mother mind you, while I was in the doctors waiting room waiting to get my hernia surgery checked out. The mother was a young black woman and she had given the child a dollar to get something later after the doctors visit for whatever it was she was getting checked out. When the boy began acting up, she put in force the Parental Indian Giver clause, that's right 'The P.I.G. clause' (which is legal in all 50 states for parents to take back what they have given their child under any circumstances).
Well the child immediately had none of this action so he said....and I am quoting a 2 year olds dirty little mouth "Gimme my money back!!!!! gimme my money back!!!!! gimme my money back nig*a!!!!!" I have never seen a child go horizontally out of a room as fast as that one did. Upon reentering the room 3 minutes later, the child went to a chair across the room from the mother and sat silently the entire rest of the wait. The whole thing was a blur for me, I can't immagine what it was like from that childs vantage point. What's the world coming to when a 2 year old child is calling his mother a 'nig*a'?
