At the Invictus event a couple of years ago (can't remember the official title) she was waltzing through the crowds, eyes on the camera, when she came across a child in a wheelchair. She bobbed down beside him, grinning for the film camera, without either interacting with him or his family or acknowledging them in any way and then - up she jumped and went gaily on her way, spreading joy everywhere among the afflicted.
It was shocking to watch - utter, utter callous self-centredness and empathy failure. The boy was merely a convenient prop for her image - not so much there and then, but in the film to come where you can tell she thought the scenario would look just great!
I'm no Diana-worshipper, but I can imagine how differently Diana would have behaved in this context. The most restrained comment I can make about Meghan is that she's a total piece of work. I am baffled by anyone who STILL cannot see this.
