Well I would agree with you but my father does this alot. It will be fine for a few months then out of the blue he will go on rants. It's like a drunk but he doesn't drink, ya know? He has a messed up brain and has bad memory all around. He forgot what happened earlier already and was talking to me like nothing happened but give it a few weeks and he will do the same shit and it'll be like clockwork.

Happy turkey day everyone!!!

-Cheers

Just don't forget, if it his accident that is making him like this, it isn't the real him when he's flipping out and he isn't just naturally aggressive. I have a friend who's dad was in a motorcycle crash a few months ago and he's been a bit spacey and sometimes violent too. Don't let him get away with it but remember why he's doing it.
