How to not only seriously irritate, but also make me want to kick your fat ass

Tell me that I can't go to the library after class to finish my project that is due at 8 a.m. TOMORROW MORNING because I have to be here to let Natonya into the apartment. And why do I have to do it, what important task is keeping you from letting her in? Going to some old guy's house to play guitar. Because that is TOTALLY MORE IMPORTANT than a trivial thing like my fucking project for GRADUATE SCHOOL. Bitch.
