Milk
"Honestly Elphie, I don't see how you can drink that stuff plain."
Elphaba smirked as she took another gulp from her cup of milk.
"Well excuse me for not preferring my milk to be pink."
"I've told you already, it's not the color I like, it's the strawberry flavor… The fact that it's pink is just a nice bonus."
"You've already given me a make-over, so can you leave my breakfast alone?"
"But Elphie, it's just so plain!"
"I don't care how good you say pink goes with green," Elphaba retaliated, "I'm not going to let you Galindafy my milk."
