YKYOW Royalty when...
You correct tour guides at stately homes.
(I have done this at least three times, at Windsor Castle, Balmoral and other National Trust places. Most memorable was at Balmoral, where there was a lovely painting of QV with two young ladies in bustle dresses. I asked the tour guide who they were and he told me that it was Princess Victoria and Princess Alice knitting for the soldiers fighting in the Crimean War with QV. I told him that it couldn't be, because: 1. the fashion was wrong 2. Victoria was in morning clothes and Albert died after the CW and 3. really, they looked nothing like Vicky and Alice. He looked quite flustered and muttered, 'yes, yes' and nodded when I told him that it was more likely to be two of Alice's daughters or even Princess Beatrice and Louise. My mum dragged me away before I could embarrass him further. I hope they've found out who it was now!)
