Still not certain, for me, but soooo less problematic....
So, back to the grading, with greater motivation to finish it today.
EDIT: Oh, I also had a great "WTF?!" moment this morning when I opened my refrigerator door and found an apple sitting there that I clearly remembered having sliced up and eaten the day before (if apparently in a dream). It was a great sort of Matrix, reality-reset moment....
