Smell
"Elphaba," asks Galinda, "what's your favorite flower? Mine's a rose!"
Elphaba smiles.
"Why a rose?"
"Well, they smell nice! And they're pretty!"
The green girl laughs.
"But they have thorns that sting and hurt you."
Galinda pouts.
"Look, would you just tell me your favorite flower?"
"Poppies. They smell so lovely they put you to sleep, and you dream of their fragrance as you waste away to dust…"
Galinda sighs and tosses her hair.
"You think too much, Elphie."
