"Hermione, I'm sorry."
"You said that already."
"Don't walk away."
"Why not?"
"Don't walk away from me, please."
"Why not? Why can't you just leave me alone?"
"Leaving you alone won't help any."
"Sure it will."
"Your anger won't fade until you have yelled at me."
"What?"
"Hermione, I know you. I know you quite well. Your anger won't fade until you've yelled at me and have said your piece. So do so: yell at me."
"You're giving me permission to yell at you?"
"Yes. Unleash your anger, it's the only way you can get over it."
"Get over it!"
