You know what I really hate?

[d_aulnoy]

I really hate busting my chops to get a task - like, say, grading - finished in order to make the deadline and be free to relax, only to discover that the system failed and the sense of being done was only a cruel illusion, only to try to resubmit to be done, really done ... only to have that self-same system deny entry.

I hate technology.

And it hates me right back.
