Is it normal that my dad yelled at me in this way?
I was helping my dad, who had had a solo alcohol mission the previous night, with some emails, and some navigation elements were being slow to load. I told him we were capped until the following day, and his mood simply SWITCHED. He ordered me to turn the computer off and we went to his annex house which essentially had different internet. He proceeded to make various quips about my mum (who I love way more than him and is way more intelligent) and her weight, cooking ability, her mental state and said he hated her guts, which was pretty distressing (They're not divorced and I haven't seen any sign of marital instability apart from the odd fight til now)
This continued for two hours till he essentially got it out of his system, during which time he called my brother a smart-ass, insulted my friends, and various friends of them he hadn't met, he told of family members on my mum's side being assholes and going to mental institutions, he said he felt "immensely stupid" for investing in the internet and other tech stuff when it didn't work, (We only got capped 3 days before the rollover date, not bad for 15gb a month). TBH I don't think I took any of what he said any more seriously than he did.
He also refused to have a full stop in a password (he had to) as he said "he was a businessman not a typist". (He's tech-tarded as fuck. I'm not joking also.)
It's as if he was looking for a reason to yell. I can't deny the legitimacy of some of what he said, mainly the economic concerns (We are in some hard times in that realm) but he constantly spouted out rationalizations on why it was my fault. He called me a thief for some reason I can't remember. (I haven't stolen from him ever)
My mum says he has ADHD and Dyslexia, both "undiagnosed", though I think he has Autism rather than the former. The two reasons why I think this: 1. He's fucking WEIRD. 2. He called my mum autistic in the heat of an argument once, which she is nowhere near, and
He's basically an impossible guy.
Is he going crazy, senile, or is he just stupid?
