Prince Louis thanks Princess Kate's parents in sweet personal note
The Prince and Princess of Wales's son Prince Louis penned a heartfelt message as he stepped out for his mother's Christmas carol service on Friday.
The six-year-old placed a message on the Kindness Tree outside Westminster Abbey, which featured dedications personally written from guests to people who have shown love, empathy and kindness.
The handwritten note on the red label was dedicated to Kate's parents, Carole and Michael Middleton, with Louis writing: "Thank you to granny and grandpa because they have played games with me."
The Middletons were among the 1,600 congregation, along with Kate's younger siblings, Pippa Matthews and James Middleton.

He later added that William quickly bonded with the Middletons, writing: "I saw a lot of William when he was an officer cadet at Sandhurst, which is fairly close to Bucklebury. So by the time I'm toing and froing between Edinburgh and London, he's become part of the family."
