My First Great Quote from "To Kill a Mockingbird"

"It's not necessary to tell all you know. It's not ladylike – in the second place, folks don't like to have somebody around knowin' more than they do  It aggravates 'em. You're not gonna change any of them by talkin' right, they've got to want to learn themselves, and when they don't want to learn there's nothing you can do but keep your mouth shut or talk their language."                                                                   ~ Calpurnia

Just like in poker its not necessary to tell all you know

Background 
Scout figured out about Calpurnia's so called double life and the way she talked outside of their house. Scout became so curious that she confronted Calpurnia about her double life. When Calpurnia made sense of it all Scout retorted by saying "But Cal, you know better" which set up the quote above.

RationaleI would consider this quote to be a Words of Wisdom quote because Calpurnia is not only telling Scout how to act but this quote has a hidden meaning as well. Calpurnia is deep down trying to tell Scout a life lesson that she will carry on with her into her adult life. The only way to learn things is through experience and Calpurnia has that experience to back up what she is saying to Scout. Calpurnia’s words here sound kind of like Atticus’s repeated statement that he wants to be the same person at home as he is in the streets. Calpurnia and Atticus offer different models to Jem and Scout of how to deal with a world that often can’t deal with who people really are. She is telling Scout not to be a know it all.  No one likes it when there is always someone who thinks they are the “expert” of all things and is always telling us what is correct.  Even if you really do know things, sometimes it’s better to keep it to yourself.  My Nana had her Master’s Degree, but never told people.  When I asked her why she told me that it made people treat her different, and she didn’t want that.  She said she liked people to be themselves when they were around her.  Besides, she said it didn’t mean she was smarter.  She said she would rather impress someone through her actions, then through her credentials.  I think this is sort of what Calpurnia was trying to say.
