You get into a dorm with your new roommate, you where very happy to know who your roommate was! When you get to your new dorm your roommate is there. He's listening to music. He looks at you and says

Alex: How the fuck did you get in my dorm!

You respond with "this is my dorm, I have a key!"

He seems pissed off and says

Alex: just don't fucking bother me, I took the biggest room bitch.
