Let me be honest with you now and skip the giggling!
It is certainly a complicating relationship between these two siblings outwardly, as it shows the sis is certainly sort of a boldy minx pike, yet caring and well aware of her place and position, she wont go pushing it to hard, thats for sure. As it says; "A sister is like yourself in a different movie, a movie that stars you in a different life".
It's actually great to see that excessive fat accumulation Kim, da' notorious gangsta has taken hold of itself, understanding the importance of losing weight before he dies by heart failure.
However, I'm almost certine it's her nagging which has led Kim to the slimmer shapes.
I have to admit I'm a great bit impressed by his way of negotiating away the US-adminstration from harsh reaction, I thought he will standing down fairly quickly, faster than IR-mullas to lift the sanctions, I was wrong. He's hard as lonsdaleite, even harder and most firm!
As I see it, neither Kim the fat-Slab nor the IR-mullas will step down as it is and in a foreseeable future.
Sad it is, but it is what it is!
