My dad's like this. I'd be like this if I were a dad. Dads in general seem to only have the freedom to be a tsundere or genuinely hate you/not care about you.
Has this been your experience?
I think mine doesn't care that much.
He talks to me maybe once a year. He cares anough to not ignore me, but I get the feeling he only does it because "he's supposed to". I don't know.
I'm just saying, given all the knowledge at hand, it seems more likely that he's a tsundere and you're too autistic to tell.
