Prince William is, reportedly, feeling a "tinge of sadness" as he turns 38 on Sunday, June 21. The Duke of Cambridge was hoping to reunite with his father, Prince Charles, for his birthday but that will still likely not be possible due to the coronavirus restrictions.

Royal expert Katie Nicholl said that Prince William will still not be able to see the rest of the royal family in person despite the easing of lockdown measures in the U.K. He will, reportedly, be spending his birthday at Anmer Hall, where he has been in isolation with Kate Middleton and their children since the middle of March. 

Nicholl said that Prince William told some friends that he loves spending a lot of time with his children during the lockdown. However, there is some sadness over not being able to see Prince Charles, who has been staying in Scotland with the Duchess of Cornwall for the last three months. 

Apparently, the Duke of Cambridge has grown closer to his father in recent years. The friend told Nicholl that Prince William has had a mind shift about his relationship with the Prince of Wales. 

This mind shift is apparently preparing Prince William to fulfill his destiny as the future king. The friend said that this destiny is their common ground and it is Prince William's strongest connection to Prince Charles. 

Meanwhile, both Prince William and Prince Charles resumed their public service this week, in separate events. The Duke of Cambridge met with the first responders of the East of England Ambulance Service Trust in Norfolk. Prince Charles, on the other hand, made a surprise visit to a hospital in Gloucestershire and also met with France's President Emmanuel Macron in person in London.

However, palace sources said that these face-to-face meetings will not be a regular thing for the royals. As much as possible, Prince Charles and Prince William, as well as the rest of the royal family, will still conduct their royal engagements virtually to limit their exposure to the coronavirus. 

A spokesperson from the office of the Prime Minister Boris Johnson said that the lockdown and quarantine rules for Prince Charles and Camilla's London meet with Macron on June 18 was an exception. Under the guidelines set by the government, foreign dignitaries conducting their business with the U.K. government may be exempted from the extreme measures of ensuring that there will be no virus spread.
