Deuteronomy Chapter Question

           This chapter of the novel kind of confused me. I did not get what Jeanette was trying to infer towards the bottom of page 95. She states "And so when someone tells me what they heard or saw, I believe them, and I believe their friend who also saw,but not in the same way". I understood that she was implying that she will view the points of others but will not compare and view those points in similar ways. The part that I did not understand was where she states "Here is some advice. If you want to keep your own teeth, make your own sandwiches . . . .". In my point of view I took it as that she is saying if you want to believe something happened see it for yourself. You can not depend on what others will tell you. I did not get why she would first say she would believe it but then say make something on your own. In my perspective I take this as that something can not be proven true until you witness it yourself. My question is what is really being meant by this part of the chapter?
