For men possessed of sufficient age and experience, the secret to dancing like no one is watching is simple: make sure no one is watching. Lock the doors, draw the curtains, put black tape over all the webcams in your house, and proceed. I was going to add that you should only dance anywhere you would also be happy to appear naked, until I remembered the shower, and saunas. Obviously, don’t dance in either of those.
No such security was available to Prince William at the weekend, when he was spotted – and also filmed – dancing away to Taylor Swift at Wembley Stadium on his 42nd birthday, in a blue blazer, high up on the balcony of some hospitality suite. It’s amazing to me that seats that expensive don’t come with one-way privacy screens, but evidently they do not.
