She was a fool to skip the coronation.
If she'd gone, and taken the trouble to look hurt whenever she and Harry were snubbed... nobody would be talking about anything else today! Seriously, if she'd gone, and been snubbed, and looked hurt, and shared sad puppy-eyed looks with Harry while people ignored them, all the talk today would be about whether that was evidence of racism and snobbery in royal circles, or whether they deserved to be snubbed. And Harry's book would have a jump in sales, and everyone would be paying attention to the Harkles, and that's exactly what their brand needs.
No, she really missed a golden opportunity, who the hell knows why.
