The Duke of Cambridge spoke about the importance of chatting with family on Saturday as he met emergency service heroes to watch the Scottish Cup Final.
William, 38, chatted while watching St Johnstone defeat Hibernian 1-0 on big screens in the rooftop bar by Edinburgh Castle.
Speaking to a table of first responders Prince William asked how they had kept in touch with families during lockdown.
William said: “The funny thing is when I spoke to my family I found it so good to catch up but then you haven’t anything to catch up on because no one had done anything.”
When one guest said they had not seen their in-laws for a year, Wills joked: “Some people are quite happy they haven’t seen their in-laws for a year.”
After laughter, he added: “I love my in-laws.”
The Duke also took time before kick-off to speak to communications officer Kirsty Walker, 26, and her sister police officer Lindsay Walker, 39, whose dad Brian Walker killed himself in June 2018 aged 68.
Lindsay said afterwards: “He seems to care a lot about mental health and the importance of talking and supporting each other generally.”
“We’ve been affected by suicide and so we had a good chat about mental health and he was clearly passionate about it,” Kirsty added.
It comes just days after William blasted the BBC over its Panorama failings and Prince Harry launched a fresh attack against the Royal Family.
Harry, 36, derided his upbringing and accused his family of “total silence” and “total neglect” when he and his wife Meghan were struggling with their mental health.
He has previously spoken about the impact of “traumatic” call outs while he was serving as an Air Ambulance pilot which nearly took him “over the edge”.
