" Didn't I know, he asked, that some people found me a snob? I didn't. Our marriage was formed by the things Christopher knew and the things I did not. This was not simply a question of intellect, although in that respect Christopher again had the advantage, he was without a doubt a clever man. It was a question of things withheld, information that he had, and that I did not. In short, it was a question of infidelities - betrayal always puts one partner in the position of knowing, and leaves the other in the dark. "
