A Momentous Occasion

I must mark the moment for history. For the first time in four semesters of teaching at this particular institution of higher education, all of my classes meet in the same building, which is also the building where my office is located. And not only that! No, not only that. Each class meets in the same classroom every session. They don't all meet in the same classroom. That would be just too special. But they each have their own consistent room from day to day and I no longer have to wander around thinking, "Okay, what's today? Wednesday? That means we're downstairs today? Or is it upstair? Huh? Who are these people? I guess it must be the other room today."
