Wanna bet?

So, I was thinking about how my mom's phrase is "Wanna bet?" and if you say that, it means that she knows she is right and you better backtrack if you don't want to be proved wrong.  Immediately.  And I realized that there is a part in To Kill a Mockingbird that is kind of like this, where Scout is talking about Atticus.  Here's the part I'm talking about:

" 'Do you really think so?'

This was Atticus's dangerous question.  'Do you really want to move there, Scout?'  Bam, bam, bam, and the checkerboard was swept clear of my men.  'Do you really think that, son? Then read this.'  Jem would struggle the rest of the evening through the speeches of Henry W. Grady."

I thought it was an interesting parallel, how my mom, and Scout's dad, have these phrases that make you stop, and rethink.  I just found it...weird that these two things from completely different parts of my life kind of came together.  That happens sometimes, to me.  I like it actually, I like making those connections.
