The Duchess of Cornwall visited a tiny village school in Aberdeenshire, Scotland, just as Princess Eugenie was getting wed at Windsor Castle.
Camilla visited the primary near the royal residence of Balmoral on Friday as husband Charles attended the wedding of his niece to Jack Brooksbank along with around 850 guests.
It is understood that Friday's invitation was a longstanding one and the duchess did not want to let the schoolchildren down.
Camilla's arrival at Crathie Primary around the time Eugenie and her father, the Duke of York, arrived at St George's Chapel - was delayed due to a tree on the road in very blustery weather.
She was given a tour of the school - which has just nine pupils - by 11-year-old Logan Beedie and Zara Jones, 10.
As Eugenie and her spouse exchanged vows in Windsor, Camilla spoke of her love of the local area and its wildlife with the pupils.
The duchess later visited a new heritage centre named in honour of her husband, known as the Duke of Rothesay in Scotland, where she watched a display of Highland dancing by 24-year-old Rachael Walker, from Fettercairn, Aberdeenshire.
The Duke of Rothesay Highland Games Pavilion is situated in the Princess Royal and Duke of Fife Memorial Park, where the world-famous Braemar Gathering is held every September and regularly attended by the Queen.
Robert Lovie, of the Prince's Foundation, said: "It was a pleasure to welcome the Duchess of Rothesay to Braemar for her to see first-hand the completed Duke of Rothesay Highland Games Pavilion.
"She was enthusiastic about the building's beauty, the value of its purpose, and its ability to fit seamlessly into the surroundings."
