Well, tbh, it has kinda affected my grades indirectly. I constantly brood about whether I am stupid and that iq test lied, or if I am just overthinking. That has made me to pay even less attention, and I developed trichotillomania, and I already have a small bald spot. I stopped recently, since I am trying to relax.
And he has his good moments, when he comes home and asks me how am I, or when he asks me about science. But Thats a little rare, usually he disbelieves what I tell him, or starts questioning the sanity of the person who wrote what i read, when in fact they are accomplishes scientists from universities like yale or harvard.
I tried many times before to talk to him about parallel universes, and how they may explain the reason of the big bang. There is this theory that says that before this unverse started, the only thing existing was vacuum energy, virtual particles that popped into existence and anhilated each other instantly. So at one moment, one of those fluctuations can become a universe, just like ours, ane create many others.
What did my dad say? "thats just a theory, very implausible. They dont want to admit God did it all". And I dont want to offend you, since you believe in a god. I am perfectly fine with it, I believe in pantheism myself. But I cant believe he dismisses a perfectly reasonable and rational theory just because it doesnt fit his experience. So what i did is that I stopped talkig to him about what I read, and when he asks me what am I reading I just answer "stuff". Ofcourse , he tells me he isnt giving me any money if I dont tell him, but I dont care anymore. I am planning to get a job here at college, since they respect one's schedule.
Oh! and he always makes this argument about how something isn't true or real just because he hasn't lived or seen it. That's the dummest argument ever, since you dont see the moon's craters and marias but you accept they exist!
I talked to him about the ststistic of men who die after their wives die, which is a significantly high one, and what did he say? He of course accepted it! lol I wish that was even right. Right away he contradicted me and said how he has a few friends whose wives have died, and none of them have thoght of suicide or died, because "they have a stronger character". He is just some macho asshole, and in no way he is a role model for me. I am a guy, and I bought a hello kitty bag for my ipad, and a melody plush, and he shook his head in disapproval. In no way will I do that to my children if I ever have them. I know how all this crap feels, and I am not going to repeat it.
