Knowing that you are completely out of clean clothes... and there not being a single open washing machine. Actually, I'll expand that to having to share a laundry facility with 140 women. Do you have any idea how many clothes a dorm full of women goes through? There's never an open machine. And then if there is, the dryers are in use for the next several hours after your load finishes.
Not, of course, that I'm annoyed by this or anything.
