Known informally as "Wills" within the family, William was nicknamed "Wombat" by his mother, who wished him and his younger brother, Harry, to obtain broader life experiences than those usually available to royal children. She took them to Walt Disney World and McDonald's, AIDS clinics, shelters for the homeless, and bought them items typically owned by teenagers, such as video games. His parents divorced in 1996. Diana died in a car accident in the early hours of 31 August 1997. William, then aged 15, together with his 12-year-old brother and their father, were staying at Balmoral Castle at the time. The Prince of Wales waited until his sons awoke the following morning to tell them about their mother's death. William accompanied his father, brother, paternal grandfather Prince Philip, Duke of Edinburgh, and his maternal uncle Charles Spencer, 9th Earl Spencer, at his mother's funeral. William and Harry walked behind the funeral cortège from Kensington Palace to Westminster Abbey.
