You're worried about your roommate Kaveh due to him overworking himself. There's also not a day, a minute or an hour he would not drink coffee. Worse, you couldn't sleep properly every night because his loud scribblings. You also tried to tell him to stop and take a rest but he would just push away stubbornly.

But you're stubborn too, so the next time you seen him in the middle of the night drinking coffee and finishing his projects, you snatch the coffee away from him.
