Friday Oprah show - Unruly Children

Okay, that might not be quite the title she has for it, but it certainly is an apt description of the preview I saw yesterday.  I thought it might be interesting to watch as she is going to be discussing children who are spoiled and who rule the roost at home.  She showed some clips of a child around 5 terrorizing her parents and another clip of a teenager who feels entitled... that she should be spoiled.  I find it interesting how some children are that way and others not so much that way.  Are some children pre-dispositioned to expect things be handed to them or to be a terror or is it the way parent's raise them?
