Guys, College Vampire
They can’t get into their dorm because they missed the tour/orientation whatever and they have to wait outside until their roommate shows up and lets them in.
They show up early to all of their classes the first week so the professor is there to open the door and let them in, which works almost every time (There’s a class in that room fifteen minutes before his starts, so the professor doesn’t need to unlock it).
They can’t take the bus because they don’t want to bother the driver with needing to be invited in.
They always ask “hey, is your bathroom open to the public”/“hey do you have a bathroom” in stores and restaurants so they can be invited to go to the bathroom.
And of course they never get caught because they’re just an awkward, sleep-deprived goth/emo/punk/whatever who is pale, sleep deprived, and never eats in the dining hall. So a quarter (at least) of the people on my campus anyway.
