Still at work last night at 8pm (quarter grades were due this am), two of my students wandered in, one week early for the night they are signed up to give tours of the school to incoming seventh graders.
student 1: Wow, I never realized the clocks kept going after we left.
me: Yep. They run all night.
student 2: Whoa ... and do, like, does the noon bell ring at midnight, too?
me: John, how on earth would I know that?
student 2: oh yeah ... right.
