While much of my teaching work-flow has shifted digital in recent years, I still keep a paper plan book. How long that will continue, I don't know. What I do know is that as the calendar turns towards spring each school year, the cover of my plan book starts to fail. The paper perforations give up the ghost one hole-punch at a time until the cover is hanging askew by a few tenacious threads. Eventually, the cover falls off completely. This tends to happen at some point in April (after spring break), signaling in one quirky way the sprint to summer. This year, though, that plan-book milestone passed in the waning days of February -- just a few days before the plastic loop split that once helped fasten my school-issued name badge to my shirt or belt. These harbingers feel ever-so-slightly ominous, though I'm not sure if these shadows cast backwards over time that's passed or forward to days to come.
