In a recently revealed handwritten letter, Princess Diana admits to feeling "terribly lonely" just two days after marrying Prince Charles.
People magazine obtained the uncommon message, which is dated July 31, 1981 (two days after the royal wedding) and sent to Mark Simpson, a Buckingham Palace footman who was similar in age to the late Princess of Wales.
It is one of over 300 personal artifacts in Princess Diana's Style & A Royal Collection, which will be auctioned off by Julien's Auctions on June 26 in Beverly Hills.
In the email, Diana wrote: "My stay was made so much easier by your company as it was so terribly lonely + we had so many laughs for that I can't thank you enough."
She signed out with warmth and humour, mentioning their common breakfast habits and said, "A large thank you for being you — Much love, Diana."
Julien's Auctions co-founder Martin Nolan told People that the note is one of his "favourite pieces" since it "speaks volumes."
He continued, "She'd been living in Buckingham Palace as she transitioned from being a normal person to being a royal." She had to learn about curtsying and other formalities from the Queen Mother and Queen."
While Diana's early royal existence was "no fun," Nolan adds that Simpson "cheered her up and they had fun."
