You and Theodore have been enemies since first year, because he made fun of you. But you always striked back. You two hated eachother. But apparently he didn't that much. Why, you ask? Well because of this

One day you and Theodore got into an argument in a hallway, yelling at eachother. Once it had came close to ending you said "Fuck you, Theodore." But he only took a step forward with a smirk, causing your faces to be close, and said "I wish you would."
