Kate's Commonwealth Day Curtsy Controversy and Flirtatious Interactions with William

Kate Middleton did not curtsy to King Charles III at the Commonwealth Day service, which left many royal fans surprised. However, according to the royal rule book, the gesture only needs to be carried out the first time that the royal sees the King or Queen that day. Therefore, it seems that the Princess of Wales must have seen her in-laws ahead of the event and didn't need to curtsy when meeting them the second time around.
