Example 1 (Disney Film, general tone):
Cinderella: (to her stepsisters) If you please, may I go to the ball?
Stepmother: (coldly) You? Go to the ball? Don't be ridiculous, girl!
Example 2 (More literary, focusing on conflict):
Stepmother: (shrieking) You will not go to the ball, Cinderella! You are nothing but a scullery maid! Clean this mess instead!
Cinderella: (softly but with defiance) But... Mother... I only wished to see the Prince.
Example 3 (Focus on humor, again depending on adaptation):
Stepsister (Drizella): My dress is too tight! I simply *must* have that extra ribbon!
Stepsister (Anastasia): And my slippers need more buckles! The Prince would never look at me without at least six!
The specifics of the dialogue change based on the adaptation, but these give you a sense of the different types of exchanges you might find in a Cinderella story.
