J.K. Rowling: The Dursleys are reactionary, prejudiced, narrow-minded, ignorant and bigoted; most of my least favourite things. I wanted to suggest, in the final book, that something decent (a long-forgotten but dimly burning love of her sister; the realisation that she might never see Lily's eyes again) almost struggled out of Aunt Petunia when she said goodbye to Harry for the last time, but that she is not able to admit to it, or show those long-buried feelings. Although some readers wanted more from Aunt Petunia during this farewell, I still think that I have her behave in a way that is most consistent with her thoughts and feelings throughout the previous seven books.

Nobody ever seemed to expect any better from Uncle Vernon, so they were not disappointed.
