One of my co-workers commented that no one heard me yelling, so things must've gone better. It was report card day today (those grades I was mentioning was for the last test that I hadn't brought myself around to grading). Some of them still think that they have a shot. I think I my worst-case problem may behave himself for two weeks, wondering if he has a snowball's chance in hell of getting a 65 or a 70.
I took advantage and chilled out for the rest of the day. Thankfully, I bought a new can of coffee, so there was a fresh pot at lunchtime.
