Self-Defeating Recalcitrance

It drives everybody up the wall: Lyra repeating what you've just said to her, preceded with the word "No," just for the sake of it.

"Drink?" "No drink." ..... "Drink please"
"Food?" "No food." .... "[Apple|Ham|Crisps] please"
"Shoes?" "No shoes."

Sometimes it takes someone she likes and respects to step in and help out.
