The Duke and Duchess of Cambridge are currently enjoying an exciting two-day trip to Scotland.
They've already visited a primary school, and a housing management group and paid a visit to the University of Glasgow.
But at the end of the first day north of the border yesterday, William and Kate took to their Twitter account to issue a rare yet heartfelt apology.
During their visit to the university, they met some of the students and other well-wishers that turned out to meet them.
But it appears there were so many of them, the couple did not have enough time to greet them all.
And in a Twitter post alongside a video of them at the university, the couple said: "So many students! Sorry if we missed you."
Today, their engagements in Scotland continue with most focussing on the topic of mental health.
Meanwhile, also yesterday, William joked about Kate becoming broody when they visited a school where she cuddled a baby, sang along with children and spoke to young pupils.

They visited St John's Primary School in Port Glasgow, where they took part in a 'Roots of Empathy' session.
Mum-of-three Kate looked delighted as she cooed over 10-month-old baby Saul Molloy - and it prompted William to joke: “Can you get my wife out of here before she gets broody?”
Later, the couple met people helped by the housing, care and property management group the Wheatley Group at one of the organisation’s sites in the Kennishead area of Glasgow.
They learned how the group is helping to transform the lives of disadvantaged or vulnerable people, including those at risk of homelessness.
The couple met mothers whose children receive books through a partnership between the group and the Dolly Parton Imagination Library.
These engagements will form part of a UK-wide tour for the couple to mark the Queen’s Platinum Jubilee this year.
Earlier this week, it was announced that they would also be visiting Wales over the Jubilee bank holiday weekend.
The Earl and Countess of Wessex will visit Northern Ireland and the Princess Royal will visit Scotland with all the members of the monarchy attending public events marking the Platinum Jubilee.
The Prince of Wales and Duchess of Cornwall are likely to be in the capital attending events over the four-day weekend in June but it is not known which engagements the Duke and Duchess of Sussex will participate in.
During her Diamond Jubilee celebrated in 2012 the Queen and Duke of Edinburgh made an extensive tour of the country over a three-month period.
