“Be good, let me kiss you, just once.”
“Be good, you must listen to me. I’ll pamper you.”
“Be good, stay away from him. I don’t like it.”

“Be good and stop throwing a tantrum. Divorce doesn’t exist in my dictionary, only... a deceased spouse does.”
Resolute and ruthless, his hands are stained with blood; he’s cold and unfeeling...
