Now, the reason why is becoming clearer. At a briefing Wednesday for theannual royal financial report, it was revealed that Charles, 73, is a prolific letter-writer, penning more than 2,400 a year — almost seven a day.
A royal source says it was “touching” how letters from the public might catch the prince’s eye because of “what they were saying or the kind of issues they were raising.”
“Very often when members of the public write to him they may be surprised to see on their doormat a personal letter to them from the heir to the throne,” the source adds.

A lot of his replies are also part of his official state business, such as thank yous to the President of Rwanda, who hosted Charles and Camilla earlier this month.
Details of Charles and Camilla’s visit earlier this month withPrince Harry,Meghan Markleand their two children were also revealed during the palace briefing on Wednesday.
A source says it was “wonderful” for Charles and Camilla to spend time with the family.

“It was a fantastic visit. The prince was delighted to see his grandson and meet his granddaughter for the first time,” the royal source says.
“The Prince and the Duchess [of Cornwall] were absolutely thrilled to see them,” the source continues, as Charles had not seen his grandson Archie “for a bit of time.”
