I don’t know why Broud says she is disrespectful, he thought, watching her go. I can’t see anything so wrong with her, except that she is remarkably ugly.

Beauty is in the eye of the beholder, and the men in this book are unable to think pasttradition. The tradition of putting women down to stop them from their true potential of overpowering the men.
