you're at work
you can't really leave
there's nothing to do (well, there is but you don't have any reason to do it right now)
it's a skeleton crew
your eyes are burning from staring at a monitor
you've surfed everywhere you want to surf
you've got nothing to blog (but this)
you've exhausted conversation with your co-workers
you're thinking of the pound cake that you foolishly left at home.
