The first day of school is a big deal for any child, even for a future King.
So when Princess Diana 's five-year-old son Prince William was set to head out for his first day, the proud mum gave her eldest child some wise words of wisdom to put his mind at ease.
Diana, along with her then husband Prince Charles, went along to drop him off at Wetherby Prep School in Notting Hill, London.
But before setting off on his big adventure, Diana gave him a quick talking to, to prepare him for what was to come, reports the Mirror.
Ken Wharfe, former bodyguard to Princes William and Harry, told Yahoo's Royal Box :"Diana said to him in the car, 'When you get to school there are going to be lots of media and lots of photographers, you've got to behave yourself.
"You're going to get this for the rest of your life."
And his reply was priceless.
When the family got out of the car, William made a cheeky remark to the photographers congregating on the street outside of his school.
Ken recalled: "William turned around and said something which was extraordinary. He said, 'Don't like 'tographers.'"
But he still managed to give them a small wave before he walked in.
Kate Middleton also had some touching words for her daughter Charlotte on her first day of school.
Prince William and Kate looked as proud as ever arrived as they arrived at Thomas's with George and Charlotte, who was seen nervously clutching to her mum's leg in photos.
Despite shyly hiding behind her mum, she shook hands with headteacher Helen Haslem who greeted the family warmly.
But before she headed off through the school doors, Kate whispered some words of encouragement to her daughter Charlotte to put her at ease.
In a video showing the family arriving for the special day, Kate, who was holding Charlotte's hand, can be heard saying: "George will have to show you the way" - How sweet!
