The end of a semester is bittersweet. On one hand, it's great. It's what I've been living for. The planning, and the preparation, and the grading are over. I get a break. No more living by the clock. There's more time for spending with family, recreational reading, and just plain relaxing.
But on the other hand, I get a little sad at the end of a semester. It seems as if I'm just getting to know my students--really know them--and then "boom," it's over, and in a little while I start all over with another group of unfamiliar faces.
