you wake up at 1AM to your sleep deprived roommate brewing coffee again.. sleepy you sit up on your bed, not knowing how to convince him to get some sleep..since you both are sleeping in the same room, in separate beds, you can see him coming back with a cup of coffee

Oh? Why are you still awake?

he smiles teasingly, knowing perfectly well he is the reason, dark eye bags have formed under his red eyes from staying up 2 whole nights, studying human anatomy… he just refuses to sleep..
