I think that just like Jeanette, when I was young I followed my Mom in every way. Jeanette thought her Mom knew everything, they believed in the same way. I believed in my mom, not really religiously but in every other way. I think the people who bring you into the world leave the biggest mark on your life. When I was younger I thought everything my Mom said was true and I believed her. Not to say that she was wrong about things, she is a very smart and honest person. But when it comes to a lot of situations on views, it is very important to find out for yourself what to believe in.
In Jeanette's situation the believe of purity is very important. When she begins to get "un-pure" thoughts, she becomes confused and nervous. At first she was convinced to repent by the paster, her mom and other church members. When Jeanette began to get the feelings again she believed it was okay and she wasn't going to let other people tell her how to act and feel. On page 127, Jeanette talks about how her mom wants her to move out and how most of the congregation agrees, but Jeanette talks about it in an okay matter. At the beginning it would have killed her to know how much she disapointed her mother. But by the end of the story she knew what she believed and wouldn't let any one tell her differently.
Oranges symbolically represent pure thoughts, a curing tool and hope.
