what's the homesickness equivalent?

Things I didn't realize I was going to really, really miss about MIT: living with lots of people who enjoy a good intellectual discussion/argument, who like devil's-advocating other points of view, and who're willing/able to make smart, logical arguments and acknowledge when a point is backed up by emotions/traditions rather than logic/facts (not that that totally invalidates it, just that it means you can't reason with it).
