Never really grew up with Arthur but watched that episode and it pissed me off. I mean, after how many times of telling your sibling to"fuck off" are you then allowed to hit them. It was a push. Fell on her ass, confused then realized waht happened, being shoved goes into crybaby mode. He spends the rest of the episode ostracized with the "but you hit your sister". . Anyone with siblings has hit or been hit over stupid bullshit so don't give me that. At the end of it all she goes "but I'm a child" excusing herself of any responsibility but in so acknowledging that means she should know better. DA FUCK!
