This kind of thing I've seen previously and there are plenty videos of this kind of behaviour online as well.
It generally goes with the whole family having to constantly walk on eggshells, play nice, speak quietly and when things aren't going so well there's door slamming accompanied by a lot of huffing footsteps, tantrum throwing and swearing at anyone in the vicinity.
It's DEFINITELY not a healthy environment for anyone in the household and I feel so fucking sorry for kids having to live with that as a "role model" as that is just not someone to look up to at all.
This sort of behaviour tends to perpetuate as it's generally learned behaviour. It's sad really, especially considering that the cycle could rather easily be broken.
It takes work though and these types you speak of would never admit that their behaviour sucks ass so it is then left to the next generation to unravel the shit and to have to undo it. Kind of unfair if you ask me.
It is unfair, but life is generally, or can be. It's up to those who have it to seek change, to own the thoughts and attitudes that bring about actions to affect change. I know it can be done. You did it.
