Where's Hari?

Okay, this is getting weird. I got all moved in and said goodbye to my folks, but my roommate had squeezed her entire extended family into our common room so instead of unpacking I decided to go try to find Hari.

I can't find him anywhere.

Well, okay, I mean his phone is off and I wandered around the Yard for like an hour hoping I'd run into him, but no luck. He didn't submit a listing to that freshman facebook thing (do you think that's where they got the name for the real Facebook??), but that's hardly surprising.

Is there a way to find out the dorm room of another freshman? Help!
