Alright, hell, Seriously guys?
You understand the law, right? You understand the possibility of things happening if you don't obey it...right? What she did was illegal, and she only got spanked with an object by her parents. That happens to me occasionally, except my parents do it with a wooden stick. And they stop after 2 - 3 minutes. Alright, I can understand it happening to me for 7 minutes with a belt, it would hurt like the day Chuck Norris jumped inside the suns core. But the thing is, the pain goes away over 2 hours, and then you go and apologize. She could've screamed "Sorry, please, I'm sorry!" Or some shit. Any properly raised child would have done that. But apparently, she wasn't properly raised. Which brings me to my conclusion, I think both parties are stupid, the child for not recognizing the good from the wrong, breaking the law, and repeatedly doing a mistake. I guarantee you, 110%, no father would ever do that unless it has happened more than twice and warned beyond the limits of warnings not to do it again. And I think the father is a retard for not knowing how to properly raise a child. I support his beating even though it was terrible to watch. It's not child abuse, she's 16 years old for crying out loud. I fell of a motorbike a couple of times and I'm 16. I don't give a fuck about gender, but I took it like a proper 16 year-old and didn't scream, shout, then try and get her father back. I do say though, the fathers beating exceeded the limits in my opinion, but since he's the father, he can beat her up as he wishes.
tl;dr - I think the father didn't properly raise the child and that the child is a spoiled brat.
