...When William was 26 and became Royal Patron of the Child Bereavement Charity, he told the Daily Mail that he still thought about his mother every day.
He said at the time: 'Initially, there is a sense of profound shock and disbelief that this could ever happen to you. Real grief often does not hit home until much later. For many it is a grief never entirely lost."
Despite it all, Prince William, Duke of Cambridge, grew up to be a dignified and much respected royal. He is very different from his young brother Harry, who has always grabbed their headlines more and is, perhaps, a little more unconventional.
Prince William, 34, Mr Sensible, second in line to the throne, is a great family man, ultra sensible and calm. And people will be very glad to see him in Derby on Wednesday, November 30. Buckingham Palace tells us he will tour the city's train-maker Bombardier and aero-engine firm Rolls-Royce.
He will then visit the Padley Centre, in Becket Street, Derby, to see the work of one of the city's longest-established and largest charities working with vulnerable people in the community.
The last visit should come as no surprise. The prince has long since shown his caring side and compassion.
