CHRISSIE: I was trying to find a tissue.
ISABELLA: You are lying.
CHRISSIE: OK, I was trying to find something to prove that you're not the poor little peasant girl you make out to be.
ISABELLA: You don't believe I am poor?
CHRISSIE: Oh yeh, I believe that all right, it's the little brother I don't believe.
