It’s five on a Friday evening, which means most everyone’s gone for the weekend -- save for the one lady struggling with the printer in the front office and the odd teacher, Miranda’s on her own.

     Which is for the best, really, because as the school’s night janitor she’s cleaning up the students’ messes half of the time.

     The other half of the time, she’s causing them.

     The cart she’s pushing knocks into the corner of an cabinet open, and there’s a resounding crash as the thing wobbles and its contents spill to the ground. Miranda, as the epitome of regal gracefulness, ends up stepping on a stray pen and slams into her cart, sending them both toppling onto the floor.

     It’s only five-fifteen.
