Sweet Story

Siobhan Vivian is coming to my neighborhood!  And I am so glad I just finished Stay Sweet! One of the things I really loved about SS was that the teens in this book actually act and think like regular people, not poets or people who understand everything and know exactly what to say at exactly the right time.
I won't call out any specific authors, but have you ever read a book in which a character always has the most insightful thing to say in any situation?  And they are also able to quote a 14th century mystic to back it up their position?
In SS the main character experiences the death of someone.  Her best friend says things like "Don't cry!"  "It will be okay!'  "Everything happens for a reason!" and behaves like a REAL person! 
Or maybe just like I do.  Because I don't always have the right words.  And I know that I have asked people not to cry, when they had every right to do so.  So I appreciate that Vivian shows characters who make the same mistakes.
