Mate, I honestly don't understand why you keep arguing with everyone. Is there anything to be gained from your point about it being 'obvious'? Not much, clearly.

I get that mummy and daddy have spoilt you and that you're used to getting your way, but that doesn't mean you need to win every argument - especially when neither side (here, at least) has anything to gain from it. It's more a 'almost certainly lose' and 'certainly lose' situation and no one has their hopes up but you keep steering the ship into the wrong direction.
