Although to the reader it is clear that her dad is an abusive, delusional, crazy, alcoholic, she claims that she would never stop believing in him. She sees the good in her dad, she doesn’t see the negative things. Her siblings Brian and Lori notice the terrible
attributions to their father's character, like his drinking and gambling, his cheating and abusive words and actions toward their mother, and his inconsistency. Jeanette is always trying to reassure her siblings that he will fulfill all of his promises, like he will find gold, and he will build them their glass castle. Jeanette still doesn't want pity.

They know they must protect themselves from them. She fails to understand her Father's reasoning, and why her mother follows along and doesn’t ever stand up for herself. Jeannette knows they need help, but they won’t ever change, again, a reason why she must learn to protect herself. Jeanette's delusional father and dependent mother will leave her scarred for her entire life.
