What becomes the focus of their quarrels?

Their quarells are focused on misunderstandings. Caludia is whipped for reasons she doesn't understand, her mother is acting strangely, Frieda is frightened because she's been touched inappropriately, and Frieda's worried her father may go to jail because he shot at Henry. Tension hangs in the air and fuses are short, but there is not specific reason............ there are many.
