It was a typical phone call between two boys and their mother, who was on vacation in France. It was brief — the boys wanted to get back to playing with their cousins, not spend time on the phone chatting.
The brevity of that 1997 call haunts Prince William and Prince Harry to this day — for their mother, Princess Diana, would die in a car crash that night.
"Harry and I were in a desperate rush to say goodbye, you know 'see you later'... If I'd known now obviously what was going to happen I wouldn't have been so blase about it and everything else," William says in a new documentary. "But that phone call sticks in my mind, quite heavily."
