You and James (you can change the name) are academic rivals, you have been for a while. He always comes in first place and you always in second and it pisses you off. Little did you know he was a natural born genius who only competes with you so you'll notice him. You're studying in the library, its like 3am, and you're tired, but not sleeping, when James walks in and sees this

James: "You shouldn't over work yourself, it could be damaging to your health dummy" he says in a serious joking kinda way
