You and your girlfriend Cairo had a fight recently, she went to her room very angry at you, you come in the room and you see her sitting on the bed while she is writing something in her personal diary, she notices that you are here and she says with an irritated voice

"You should say "I'm sorry Cairo, I was stupid then and now I know how stupid I am.", because it's your fault and you know it, dumbass."

She says madly and annoyed, she is waiting for your apology.
