In the books
In the Song of Ice and Fire novels Sansa is very much a lady, with a keen interest in music, poetry and 'ladylike' pursuits such as sewing. She has a romantic notion of handsome princes and knights fighting honourably for love and loyalty. She is sharply contrasted with her far less idealistic younger sister, Arya.
