Queen Elizabeth was short and to the point with her letter writing as a child.

To celebrate Queen Elizabeth's 90th birthday, the public relations arm of the British monarchy has taken to social media to get hip with the kiddos and bombarded sites like Instagram with throwbacks to the Queen's glory days. Those being when she was a kid.

Take the following post, showing the very first letter Queen Elizabeth (known to family as Lilibet) wrote to her grandmother, Queen Mary.

This is the first letter ‘Lilibet’ as Princess Elizabeth was known to her family, ever sent to her grandmother, Queen Mary. #Queenat90 #fromthearchives

You're supposed to read this in your head as if one of the daughters from Downton Abbey is speaking.

How extensive a doll house is it that it's taking ages for the kid to unpack? Is it life-sized? It's possible that every time we look at Buckingham Palace we're just seeing at a really grandiose dollhouse. Is Prince Philip really just an elaborate Ken doll? Potentially.
