The Duke and Duchess of Cambridge have just visited Southern California and of course the media covered every moment. Upon their arrival in Los Angeles from Canada, I noticed something that I don’t think everyone did, but that could be very telling of the royal relationship.

After William and Kate disembarked the plane, they went through a receiving line to be welcomed by Governor Jerry Brown and his wife, Mayor Antonio Villaraigosa and other dignitaries. Will went through the line first, followed by his bride. They were greeted, curtseyed to and shook hands with each person graciously. When Will was finished, he made a bee-line for the Range Rover and got in the back seat without a glance back. Kate completed her duties a minute or so later and went to the back seat on the other side of the car.

What is unusual about this? Since the British are such sticklers for etiquette, they should be practicing it in their marriages as well as amongst commoners. The gentlemanly thing for William to do would have been to wait for his wife to shake the last hand and then walk over to the car with her. Ideally, he would walk her to her side of the car and help her in before entering the car himself.

This may be a small thing, but it shows respect and consideration. I get that they’re both on a schedule and being shepherded around by security. But in a marriage, there is a kind of radar that keeps you aware of where that other person is at all times. I get that William is the prince and probable heir to the throne. But whatever happened to common courtesy and “ladies first?” If I were in Kate’s position I’d be saying to my hubby: “Hello? Wait for me!” Of course it’s not good form for couples and especially royals, to correct each other in public.

While I’m on the subject, yes, it was a lovely gesture that William gave Kate his mother’s ring. However, I do believe that Kate deserves her own ring as well. Why have Diana’s ring be her engagement ring? After all, even though Diana’s ring is beautiful and historic, it did originate from a marriage that is widely known as unhappy and that ended in divorce. That’s a lot of baggage to be carrying around on your finger. Already Kate is being compared to Diana and this will inevitably follow her throughout her lifetime. Kate is her own person and this is a new relationship, so I say give her a new ring.

Kate has a lot to put up with. Every bride has to deal with in-laws, but Kate has to do it under the scrutiny of the world. She had her wedding in the same church where her husband’s mother had her funeral. She’s a good sport to go along with her new family in all these decisions and I know this will go far in keeping Will and Kate together.

The royal couple is sure to get lots of attention wherever they go and whatever they do. But they need to remember that it is the attention that they give to one another that will be what makes this marriage succeed. It is both the attention that they give to each other in private, at home, when it is just the two of them. And it is also the attention that they give to each other in public. I remember hearing from body language experts about the sweet glances they gave each other during the wedding ceremony and how that was a good sign of a true loving relationship. The world is watching! The pressures of the position will be there and there will be obligations and schedules and demands. But the smallest reassuring glance, the hand on the back as a guide and the simple act of waiting for the other person to finish before going ahead with the next task, that will make all the difference.

This royal marriage is only a few months in and as time goes on, these simple courtesies will mean more and more. I would advise William to get in the habit of being a gentlemanly husband now. A husband with good manners is a true Prince.
