Honest question: What are the odds of fraternal twins being accidentally separated at birth?

Facebook is a wonderful thing, really. My fellow freshmen already have a Facebook group and I'm proud to say, about 5/6 of the class are members. We're clearly very plugged in. Anyway, most of the class' room assignments have been mailed out, and so begins the "Post Your Dorm and Roommate" discussion topic. There was a flurry of excitement, and since so many of us (me included) did the "friend everyone in your graduating class" thing that I've since learned is a major faux paus, our newsfeeds were full of roommates and hall mates talking. (By the way, I maintain that if your college is small enough, friending people isn't a big deal. Besides, you can always unfriend them later if they turn out to be a bitch.)

I, like many others, posted my dorm and room assignment in my status. Not long after that, a girl commented asking if we were hall mates. Although we technically are, since Dandelion East and West are connected by a study lounge and are really just the same building, she had made a mistake. Honestly, it was probably the best mistake made in the history of the world.

We discovered we have a shitload in common. To the point where it's actually really scary, and if she weren't 7 inches taller than we, I would have thought we were separated at birth. Anyway, we've been doing the wall conversation thing for the past couple weeks, and I have a feeling she'll turn out to be my best friend at Hearst. We're in the same bio class too, which is awesomesauce.

She'll now be known as Lilly, as in Lilly Kane. (Another Veronica Mars reference. For god's sake, just watch it already.)
