c20H25n3o: Although your analogy is highly flawed, I'll respond to it anyway.
One brother you are particulary close to because you share the same outlook on life, the other brother you love ( because he is your brother) but you dont think he has done himself any favours by some of the choices he has made despite the fact that he is rich and outwardly seems to be doing very well.
This part is irrelevant. It goes even more against god if he has made such a distinction by this point. Further to which, the rich brother would have been Abel who dealt with livestock as opposed to apples and potatoes.
The brother you are close to always seems content with his lot and he makes sensible choices despite being poor. The other brother brings shame to your parents because he does terrible things that only you and they know about.
This part is irrelevant because there is no justification for any of it. It does not say Cain did terrible things, it merely says he tilled the soil whereas Abel was a shepherd.
Your father then turns round and rebukes the rich brother saying "Come on, you could have at least gone into a shop and chosen a gift! Anyone with money can just stuff money in an envelope!" Your mother agrees and gives the rich brother 'one of her looks'.
I would consider them awful parents, and although I might prefer one specific gift - the same gratitude and love would be showed to both of my brothers. Maybe it's different wherever you come from, but in my country we have manners.
Besides, this is also flawed, in that both brothers actually brought what they produced. Abel who worked with animals bought a dead animal, while Cain who worked with fruit, bought fruit.
If one of my brothers who worked for a car company brought me a car, and the other brother who worked for a toy shop bought me a tamagotchi, I could not "discipline" one of them for bringing me something I didn't like- or if I did, it would be plain as day that I'm a complete asshole.
The rich brother storms out pushing past the poor brother on the way out.
Which brother pleased your parents?
god has parents? Obviously you'd mean who pleased me, and I could only say "both", in that they'd both brought me their produce, neither had forgotten to do so, and even if I preferred one present over the other, it would not in any way mean anger shown at one of them. If I did that, I'd be an asshole.
Whose gift actually cost more?
Neither.
What should the rich brother have done when your parents said what they said concerning his gift?
"Shit, you're bad parents". Or failing that, he could just say what they said: "It's the thought that counts".
Which gift pleased you most and why?
We all have particular tastes, and as such one would be our favourite present. This doesn't mean we show anger to the other brother because his present is inferior, unless of course we're mannerless assholes.
