Prince William rarely talks about his mother, Princess Diana, but when he does it's absolutely wonderful. The British royal attended the 21st anniversary dinner of the charity, Child Bereavement UK on Thursday where he gave a speech that honoured his late mom, E! News reports.

She attended the charity's launch party many years ago and now it's his turn. "Twenty-one years ago last month, my mother attended the launch of the Child Bereavement Charity," he told the crowd. "Fifteen years later, I was honoured to be invited to become Patron of Child Bereavement UK to continue my mother's commitment to a charity, which is very dear to me." The charity, which is run by Julia Samuel, a close friend of Princess Diana's and Prince George's godmother, helps children of military families, suicide victims and terminally ill parents cope with the death or inevitable death of a parent. "What my mother recognised back then-and what I understand now-is that grief is the most painful experience that any child or parent can endure," Kate Middleton's husband said, referencing the pain he felt when his mother died in 1997. "But my mother was determined to help those in need and she would have been immensely proud-as I am-of all that Child Bereavement UK has achieved these last 21 years." Although he said he has "witnessed firsthand" how the charity brings "warmth" and "comfort" to children during the "darkest" moments of their lives, Prince William admitted that he gained even more perspective once he had children of his own. "As a father to two young children myself, I now appreciate it all the more," he said. Prince William has been opening up about his family a lot recently, giving an update to host Professor Christopher Doson about his son and daughter Princess Charlotte during a visit to St John's College at Cambridge University earlier on Thursday. "He said George is very lively," the professor dished to reporters "and Charlotte is very lady-like. He said they were both delightful, of course".
