In my favorite chaperone what does mama mama mean when she says “you have brought shame to your father and this family”

Explanation:

The number one key element was probably the fear of Russians who are the main enemy.  I know that Russians are the main enemy because of the text saying, "for behind him he knew full well were the dreaded Russians, toiling through the swampy lowlands and over the steep divides, bent on no less than the extermination of all his people...He would have marveled that a whole people—women and children and aged—could travel so swiftly, had he not known the terror that drove them on." The author also uses Kinoos to fuel the story of how brutal they were in detail.
