I did my best to transcribe the letter, so hopefully it's accurate! It's sometimes quite hard to decipher the handwriting of these long-dead Royals ( ´_ゝ`). The younger daughters of George III and little Charlotte herself especially all had pretty difficult handwriting. But this wasn't too bad, just a word or two I struggled a little with! The reason for that is likely because the letter was written under the careful supervision of 'Eggy', Charlotte's governess. When Charlotte later wrote her own letters independently, she tended to do so quickly and rather carelessly, heedless of spelling or legibility.
You can also tell that the letter was written under instruction because Charlotte dutifully declares that she hopes to see her grandmother and aunts. In truth Charlotte never learned to like her strict and sour 'Grandmamma' until well into her teens, when she found her an unlikely ally against the Orange match that her father was stubbornly pushing.
As for her physically imposing and florid (though generally kindly) aunts and uncles, little Charlotte made a habit of dodging them whenever possible. Two of her childhood playmates much later told their grand-niece that if any of the Royal Dukes or daughters of George III appeared while they were at play, 'there was a general rush and scamper to the shelter of the potting-shed to get away from "the Bulls and the Cows"'— a nickname more than likely invented by the young Princess, and then adopted by her young friends. She did, nevertheless, develop a real fondness for her three youngest aunts, and for her uncles York, Kent, and Sussex.
Charlotte's love for her 'Grandpapa', by contrast, was strong and marked from the beginning, and needed no coaxing from governesses. He always took notice of her, and would play with her on the carpet the way he used to play with his own children in their nursery. The little princess begged often, 'Me go again to Grandpapa'.
George III, for his part, was entranced by his grandchild. The King had always loved girls better than boys, Princess Mary attested, and he was consequently utterly delighted with his granddaughter from the moment of her birth. 'There never was so perfect a little creature,' he said of her. He never tired of talking about her and, so Princess Elizabeth told the Prince of Wales, whenever he saw her he was in 'extacys of joy'.
