I thought this answers a thought i had in the v&a. ( mentioned in the post when i spoke about what it was like to be dyslexic in medieval times.)
ok, so 1st thing i feel i need to do hear is give a bit of background to who Tywin Lannister actually is and Who his son Jamie is.
Tywin is the head of his house and is the grandfather to the king. his oldest son jamie is one of the most famous people in the kingdom and a renowned swordsman. jamie is confident cocky and doesn’t take anything too seriously. Tywin is a strong, cold man who is strict. and renowned battle commander, who doesn’t take no for an answer. because jamie is his oldest son he will be the person to inherit his castle and lands and his responsibilities. which means it is vital that he can read.
