I've been in the office for about an hour and a half now. I've been furiously responding to e-mail sent to me yesterday (I left at 1500, just because), and have been furiously updating status reports.
And, thus far, every reference to today in anything I have written and subsequently sent reads "Tuesday". (if you haven't noticed, today is Wednesday....my cube neighbor just confirmed that for me)
This is gonna be a long rest of the week.
