On Monday, a student in the Graduate Course noticed that the table in the Seminar Room in the Department was quite dirty. It probably hadn't been cleaned since we moved into the new wing of the building in 2007. We have our department meetings in there too, virtually all the Graduate courses, and some dissertation defenses. The room gets used a lot. So before class on Wed., I brought some lemon pledge from my office and some paper towels from the bathroom and cleaned that table. The students who were arriving began to help me, of course, they weren't going to watch me without pitching in, so when the student who had earlier noticed the condition of the table arrived a few minutes later, she said "They cleaned the table!" (Yes, they did.) The table will be relatively clean at the beginning of the Fall semester, because the room isn't much used in the Summer.
This is not a metaphor for something else, but just a suggestion that you can have a clean seminar-room table if you want.
