The school year is nearing completion: just under two more weeks remain. Everyone — teachers, students, administrators, custodial staff — everyone in the building is counting the days.

Such an odd thing: we’ve spent 170+ days working together, and we’re all sick of each other, rather like a family on a long vacation. A bit of time apart and all would be well. Yet “a bit of time apart” is impossible: the students move on, and we teachers remain, waiting for the next group.

It’s as if we’re on a cosmic treadmill. We take a few steps with the kids, and though we all (teachers, students, parents, administrators) keep walking, the students slowly move on ahead of us teachers, occasionally looking back with a smile of thanks, occasionally staring straight ahead, occasionally — tragically — looking down.

“I’m so sick of all this,” we all mutter, but come what may, there will be tears on the final day, and I’ll probably be accused of laughing at someone’s tears as I was last year. “No, no, I’m not laughing at you,” I’ll insist. “I’m just smiling because it’s all rather sweet.”

It’s this time of year that I start making resolutions for the next year. Knee deep in all the mistakes I’ve made this year, I resolve not to do this or that, promise myself to be more systematic about some thing or other, commit myself publicly to more of this, less of that. I’ve a six-page, detailed outline of changes I’ll be making in one course next year, and I’ve only just begun recording my thoughts and plans. (A lesson learned from last year: all the brilliant ideas one has about changes to this or that unit tend to disappear the day school is out.)

And in the midst of all this planning for next year while making sure this year ends positively and productively comes a call from a parent. The long conversation includes a story about how her son came into my class apprehensive. Now he admits that the class is “alright” because I’m a “cool” teacher.

And another student sends me an email: “Thank you for helping me get through this year maintaining my grades.”

Bittersweet moments, indeed.
