How about glaring at you (can't talk because he has a tracheostomy/ventilator tube down his throat) and shaking his fist at you, just to make sure you don't misunderstand his meaning, as he lays there on his deathbed
Feel good sort of shit, I'm telling you, good times!
I got even with the miserable SOB, though, I was part of the team carrying his coffin 8 weeks later (yes, a female pallbearer).
Parents are human, not perfect, that's God's job. We all make our way the best we can, kids and parents. Do you go out of your way to drive his ass nuts sometimes, or are you the ellusive perfect kid and he's the shithead? If he's the shit, accept it for what it is and move forward as best as you can. I would hope you have other family members you could turn to if you're really at loose ends and he's serious about you getting out.
But I'm sorry your home life is not happy, really.
