Royals Prince William: Prince George Is 'Lively' and Princess Charlotte Is 'Lady-Like' (and Lupo Destroys the Family Lawn!) The royal dad reveals that his "delightful" kids are already showing very different personalities By Simon Perry Published on October 15, 2015 01:55 PM Share Tweet Pin Email Photo: Chris Jackson/Getty; HRH The Duchess of Cambridge Two-year-old Prince George and his 5-month-old sister Princess Charlotte are already displaying very different temperaments, says their proud dad, Prince William. The prince, 33, gave the brief insight into his two children on Thursday during a visit to the college where he studied agriculture – and which shares his formal name. The Duke of Cambridge was at St. John’s College at Cambridge University to open a new archive center, and he said his daughter was clearly the gentler of the two little royals. Professor Christopher Dobson, the Master of St John’s, told reporters after hosting the visit, “We talked a little bit about the children and he did make a couple of comments about their different temperaments. “He said George is very lively and Charlotte is very lady-like. He said they were both delightful of course.” And William brought something special to take home to his children, as Professor Dobson gifted him with the book Fitz and Will the Cambridge Cats, about a pair of feline pets that sneak into a graduation ceremony at the college. As he passed on the gift (along with a necktie in the college’s navy and gold colors), it was pointed out that the dog in the tale looked like the royal family’s cocker spaniel, Lupo. A smiling William said, “There wouldn’t be any of the lawn left if it was Lupo!” And he added, “I’ll wear my tie to the rugby.” Wales (his team of choice) next competes in the World Cup on Saturday, when they take on South Africa. The Archive Centre, which is housed in a 13th century building known as the School of Pythagoras, contains college documents dating back to medieval times, including a 14th-century copy of the Magna Carta, discovered only this year, which was on display. “I shan’t touch it, just in case,” William quipped. On Thursday evening William is expected to attend the 21st birthday dinner in London for one of the charities he backs, Child Bereavement UK. Want to keep up with the latest royals coverage?
