If I had the money she's got, I'd never be able to stop smiling.
I know the possession of money doesn't make you happy, but why does she always look so thoroughly miserable? A little smile wouldn't hurt, and might even make people more sympathetic to her.
I read somewhere, that she actually dislikes her own smile, or feels insecure about it.
I have no doubt she actually does smile at home, and away from cameras. Also, good on her not bowing down to people. If the biggest fault a person can have is not smiling, well the people would find fault in her in some other way.
