What conflicts did Kathy have with her mother and Sister?

In Part I, We learn that Kathy’s family was outright cruel to her when she first converted to Islam, and they continue to indulge in small jabs at her faith like asking her to take off her hijab and serving her children hot dogs, which contain pork and are therefore forbidden. Nevertheless, her family unites when faced with an outside threat; they stay together in Baton Rouge during the hurricane, and Kathy recalls a time that her mother berated a DMV employee who asked her to remove her hijab.

Kathy has more than one sister, but her sister Mary Ann could be considered racist.
