12. Never, ever take a selfie.

Reason: The Royals don’t want anyone to ignore them or come close to them.
Prince William and the Royal Family break this rule. If you consider it, it makes sense. It’s rare to see royals taking selfies, despite the pleading of their hordes of devoted followers.

According to Greg Agnew of Cosmopolitan claims that the reason for this is that the Royals don’t want people to turn away from them, which is a popular move made in order to capture a decent selfie. Additionally, they do not want people to feel inclined to approach them at random and strike up a conversation because that could endanger their safety.
