"I can't wait until we leave for Shiz! Father's always so over-protective, it will be nice to be on my own. All new people, a fresh new start, aren't you exited, Elphaba? It's not often one gets a clean slate."
"I expect the change of scenery will be nice. And I am looking forward to the classes, which I notice you've failed to mention."
"I'm just excited for something different." Pause. "Things will be different there, right? You'll try to control yourself?"
"Nessa, you know I can't - "
"But you'll try? Promise you'll try!"
"I'll try, Nessa, I promise."
