Josie sees Nonna’s insistence on “respect” as an imposition. Being respectful enough to please Nonna, she implies, would mean never speaking her mind or getting the truth about anything. And because of how loyal she is to Mama, Josie thinks this is just ridiculous. So the obvious solution, in Josie’s mind, is to make a plan to escape her gossipy family as soon as she can. This again reflects Josie’s youth and her desire for independence. Right now, it’s easier to hurt people (as she did Nonna, and possibly to Michael in this passage) and dream of independence than it is to be levelheaded and kind.
