After 65 years together, perhaps 'quiet' is the most welcome adjective to put on a wedding anniversary celebration.
For Queen Elizabeth and Prince Philip, it means they can embrace a little solitude on Tuesday, an all-too-brief respite from what is just another working week for the most senior members of the Royal Family.
On Monday night, they took in the Royal Variety Performance in London, a parade of talent from Alicia Keys to Rod Stewart to Andrea Bocelli. Philip's favourite? "All of them ... but to be honest we're both stone deaf."
And so it goes.
The 91-year-old Duke has a slate of engagements Wednesday and Friday, and will accompany the 86-year-old Queen to Bristol on Thursday.
If there are any plans for either of them to give in to an urge to slow down, they are keeping it a secret.
After 65 years -- all but five of them as the main residents at Buckingham Palace -- this is a couple who is completely at ease in their environment, and with each other.
Like any marriage, there have been bumps, though never in the public eye. Philip once credited the longevity of their union to the fact they have different interests. Yet they are incredibly well suited to one another. And they can still laugh.
The marriage itself is rarely on public display. The closest to maritial insights may have come on the occasion of their 50th anniversary. First, it was the Queen paying tribute to her partner:
"He is someone who doesn't take easily to compliments, but he has, quite simply, been my strength and stay all these years, and I and his whole family, in this and many other countries, owe him a debt greater than he would ever claim or we shall ever know."
From the Duke, a recipe for togetherness:
"The main lesson we've learned is that tolerance is the one central ingredient of any happy marriage. It might not be so important when things are going well but it is absolutely vital when things get difficult. ... You can take it from me that the Queen has the quality of tolerance in abundance.”
We leave you with a few scenes from this royal marriage:
Their wedding was celebrated at Westminster Abbey on Nov. 20, 1947. In the lean years after the Second World War, the Queen used ration coupons to purchase the material for her dress designed by Norman Hartnell.
