WHEN HE FOCUSES HIS ATTENTION ON HIV/AIDS

One of Diana's most iconic moments came in the late 1980s, when she hugged, shook hands with and held people with HIV or AIDS at a time when people were terrified to do so. In this photo, her sons play with children affected by HIV at a camp in Lesotho.

It's part of their royal duty to pay respects to the military, but we imagine Diana would be really proud to know her son has trained and served in the Royal Air Force and British Armed Forces for 10 years.

William may have Diana beat on this one: His relationship with Obama seems a whole lot more relaxed than hers with Reagan.

WHEN HE BEGS THE PAPARAZZI TO LEAVE GEORGE ALONE

Diana's death was due in part to her being ruthlessly, dangerously pursued by paparazzi, and William refuses to let his life be dominated in the same way. The Palace has issued warnings to the press to leave little George alone, and he and Kate release portraits regularly to satisfy the masses.

WHEN HE SENT HIS SON TO A NORMAL SCHOOL

It was a big deal when Diana pushed for William to attend an ordinary nursery school, unlike generations of royals before him. She paved the way for William to do the same with George.
