Ach - I don't care about the dancing video - I think as PP's have said there is "thing" with the 2016 / 2026 thing and she's doing it. Personally I wouldn't as I 1. don't post things like this and 2. don't think hers is particularly redolent of everlasting love - it looks a bit hammed up to me. But it's up to her. Definitely better than the twerking one methinks.
That said , for balance, I thought Catherine's video was very schmalzy. I get the message but a bit more of nature in the way of parks , pots of herbs in a tiny garden , window boxes, a dog or a cat or even feeding ducks could have gone a long way to giving it more impact.
But I am neither of these two women , and I post none of these things so mayhap ( actually definitely) my opinion is just mine and there is a world I am not part of 😊
