::millions of hugs:: I don't know what to say. I'm so sorry you had to go through this, but I'm glad you and your sister aren't badly hurt.

I know exactly what look you're talking about. My dad gets it sometimes too, though he's never been quite as violent as you described. And as for your 'he shouldn't be allowed to have kids...' I've thought that too. ::hugs you some more:: I'm just really sorry, and hopefully you can get some help. <33
