Prince William's first speech at the age of 10

CNN royal commentator Victoria Arbiter recalls the moment she saw one of Prince William's first speeches at the age of 10. Arbiter lived at Kensington Palace during her teenage years, when her father Dickie Arbiter was the Queen's press secretary. She tells Yahoo UK's 'The Royal Box:' "I suppose really the best opportunity I had to witness their personalities, I think it was probably 1992, Diana had just stepped back from a number of patronages. "She had a Christmas party at Kensington Palace and we got to go to that and while we were there, Diana was standing with us and she had asked William, as the man of the family, to stand up and make a speech. "She just wanted him to thank everyone for coming. George Michael was there, Elton John was there, a whole sea of patronage heads, there were a lot of people there. And William, at 10 years old, he stood up on a box and thanked all the guests for coming, and it was an incredibly impressive thing for a 10-year-old to do. "She was so proud, she was beaming and Harry was right next to her, and as Harry always wanted to do, he was tugging on her skirt trying to get her attention. She was like ‘shut up Harry, one minute, one minute.’ "So I think that was another example of their personalities, Harry just busy and wanting to be in the midst of everything and chatty. I suppose really what he shares with Diana is her mischievous, cheeky, naughty side, that you see play out. William embodies so many of her qualities as well but in a sort of much quieter fashion, I suppose you sort of see it in a stand-back kind of way."
