Mousebusters, that's who. The weather has turned just a wee bit cooler Near Philadelphia and this has brought some of the outdoor population indoors. Last night was Back to School Night and some mouse or another ran across the floor of the Latin teacher's room no fewer than three times. Science Department claims they have one, as well.
We'd been hearing rumors of them for about a week. This morning one has decided my space is his space. I disagree. The Maintenance guys showed up very quickly at my request; they've installed some sort of a sonic mouse-frightener in an outlet and promise to return later this morning with some good old-fashioned traps with a fine Gouda tidbit inserted.
Meanwhile, it's hard doing my work while standing on my chair!
