Boy, Is She Wrong

(I work the night shift at the security desk in a dorm on campus. One night, about 1 am, a girl tries to walk past with her boyfriend.)

Me: “Hey. Sorry, but you can’t bring him up. Check-in hours are over.”

Resident: “Oh, he lives here.”

Me: “No… He doesn’t.”

Resident: “Yeah, he does.”

Me: “I am positive that he doesn’t.”

Resident: “I don’t see why you would just assume that.”

Me: “… This is a girls’ dorm.”

Resident: “Oh, s***. I forgot!”
