The rule Meghan and Kate have to obey when staying at Buckingham Palace

Wouldn't you be raging?

Thankfully, strict bedtimes tend to phase out once you hit a certain age but not in Buckingham Palace because there's one key rule when it comes to bidding goodnight. Apparently, it's frowned upon if you go to bed before the Queen so even if you're wrecked from royal engagements and the likes, you have to stay up until her Majesty says goodnight. Sounds a bit intense. In a recent interview, Sir William Heseltine, previously a private secretary to the Queen, said going to bed over the Queen isn't the done thing, shall we say. According to The Telegraph, he said that Princess Diana, in particular, found the "long royal evenings difficult".

"There’d be an hour or so in the sitting room of everyone sitting around making conversation, and nobody felt it right to go to bed before the Queen did".

He then said that if one did go to bed before the Queen, it was viewed "as bad form".

"And Diana was driven to such extremes that she’d excuse herself and go to bed, which was thought to be rather bad form, going to bed before the Queen".

The comments were made during an interview for a new book entitled The Royals in Australia, written by Juliet Rieden. Maybe these rules have relaxed somewhat in recent times but if not, we imagine that Kate and Meghan also have to follow the Queen's lead when it comes to saying goodnight. Not ideal if you're in the mood for an early night, your PJs and Netflix...
