Her Sister
While there are certainly ways to improve your relationship with your sister, but we don’t know if sharing a boyfriend is one of them. Before Diana and Charles were going steady, he had dated her sister, Sarah. She’s the one who introduced the two when Diana was only 16 and takes credit for them falling in love. She even called herself Cupid.
In The Kitchen
It was against royal family etiquette to eat in the kitchen itself with staffers instead of in a dining room. Still, Princess Diana was no stranger to breaking protocol. Her personal chef, Darren McGrady, has said she would walk into the kitchen and eat at a countertop while he cleaned up. She would even make the two of them coffee.
