If you are marrying into the royal family, there are some serious rules to remember. When you are allowed to eat (while the queen is eating, and not a moment later), whose permission you have to ask before proposing (the queen's permission, of course), and which flowers (myrtle) must be in your bouquet are just the basics. Much of the royal protocol reflects safety considerations, but other than that: ...... Seems like it made sense at one point, but now we just do it because it's the way it's always been?

When it comes to travel, protocol tends to make a lot of sense, even if the reasoning behind it is not something the average person wants to think about. Like when Prince William, Kate Middleton, and their three children took a top-secret trip last week" Yes, it seems they had to get permission from the Queen to travel on the same plane. Isn't it fun to think about what it's like to be on a plane?

Alternatively, the rules about what must be packed for each trip also track (albeit in a sad way): according to Express, there is a rule that royalty must always pack black clothes when going on vacation. The reason for this is that they must attend the funeral immediately before or appear in mourning attire.

Even though it seems unlikely to happen, it is not without precedent: indeed, the rule stems from the experience of Queen Elizabeth II upon her return from a trip to Africa in 1952, when she heard the news that her father, King George IV, had died and would be crowned queen. According to the magazine, the queen knew that her departure from the plane would be greeted by dozens of photographers because she did not put anything black in her luggage. In the end, the queen had to send her entourage to get her clothes before she stepped off the plane.

Because of this experience, the queen reminds everyone to be instantly prepared for the worst, even if they are on a family vacation. You can see how such a thing would stick in her mind, especially as a monarch who is not allowed to mess up her hair. It gives us a glimpse into the enormous amount of thought that goes into everything the Royal Family does.
