I absolutely hate my brother. Have for years. And I have to repress it in front of my dad.
Is he the firstborn heir? I have quite a similar problem, like, I respect him deeply, but he just feels like a sort of obstacle, and the "better" son. It's great when we listen to music together and get drunk and stuff, but... It's a weird love/hate relationship. I feel you, man.
There's no love element, I'm afraid. He is the eldest son, and my dad invested a lot in him as heir to the farm. I don't mind that, though. It's him who's the problem. He constantly taunts, insults and shoves me. Then any response from me is met with my dad's anger - I should be the "bigger man" "not let it get to me" "he's just being immature" "why can't you get along with him?" So I've spent years taking insults in my home with a bland face. I honestly don't think avoiding my anger like this is healthy.
He's stabbed the entire family in the back. I'll give one example in a vast horde. He stole my mum's engagement ring, beat it into a misshapen lump, and pawned it. As a consequence of such acts, he's shunned by much of the family, which leads my dad to be defensive. He does a lot of work on the farm, and they're together a lot. He's nothing like my dad, who is a hard-working and incredibly honest person. But my dad's ideas of blood are even stronger than mine. "He's my son." The upshot is that he gets very touchy when my brother isn't given his place.
My brother systematically pits my mum against my dad. He enjoys 'stirring it'. Every meal which he is present for is stressful. And he doesn't like anyone else talking to my dad, often talking over people. And my dad lets him, which he would never in a million years do for anyone else. I'm guessing he's trying to overcompensate for the fact that no-one else engages my brother in polite conversation.
I've told my dad in the past that I don't view him as a brother. This got a strong reaction. Were it up to me, he would not be here, but it's not up to me. And I have to put up with it. A large part of it is also worry for the future. He's the eldest son. He's most interested in farming. My dad is old-fashioned and wants to give him his place. He has invested money in the farm, paradoxically at the same time as he robs it blind.
On the flip side, he can't handle his own finances, let alone a farm's.
He's not interested in animals so much as machinery.
If he gets the farm, I certainly won't be welcome - my siblings would probably feel similarly.
He has a different outlook from my dad, morally and aesthetically. He'd cut down the trees and knock down old buildings.
My dad knows all of the negatives above, on some level. But he's in deep, deep denial about it. He keeps trying to "make something" of his son and shape him into a decent human being. He thinks he has succeeded periodically until the next terrible thing he does.
That's my rant over, though frankly, with him, it's only the very tip of the iceberg. The situation is terrible.
P.S. he came in while I wrote this. Some select slurs: "faggot" (I'm not gay) "fat shit" (I'm tall and thin). In conclusion, I hate him. Which doesn't gel with my general personality, but there you have it.
