Teaching is one of those jobs that carries all kinds of asterisks and disclaimers. And it’s not a job for the faint of heart.

But one thing it has going for it — that not many jobs do — is an enforced sense of renewal and rebirth.

You spend a year going through the mud with your students. You get embroiled in their lives. Sure, you find out all about their grades and their academic progress. Definitely you discover all their little behavior … quirks. (Let’s call them quirks.) Sometimes you find out about their parents and their lives outside of school. (Often, this answers many questions you may have had previously.) And depending on what kind of teacher you are, you find out a lot more. You learn how they talk to each other. (Frightening.) You learn about their relationships with each other. (Ew.) You learn what they think of other teachers in the building. (Yikes.)

But it doesn’t stop there. By the end of the year, you know what makes them laugh. What makes them upset. You know what they’re going to do before they even do it. (Tyler, in the fourth row, is gonna ask me what a metaphor is when I talk about this story, even though I’ve explained it a dozen times this year, and when he does, Tevin, next to him, is gonna sigh and roll his eyes — and probably swat him — because he’s tired of hearing my spiel.)

You come away from the school year, in other words, covered with their gunk. And not just the students’ gunk. Gunk from other teachers and their frustrations that you have to listen to in the workroom, the mailroom, before the faculty meeting. Gunk from the seemingly endless meetings, by the way, that could have been e-mails. Gunk from the unpleasant encounters you had with parents, from the stress about the extra time you had to spend in the building at the expense of your family time, from the piles and piles and piles and piles of paperwork.

And in most other jobs, you’re stuck with all that gunk — because as soon as one job is done, it’s right on to the next. No downtime, outside from the occasional vacation (which only puts the gunk aside for a little while, to be picked up and re-applied upon your return.)

But teachers get that summer break. And what I’ve learned in my eight years (help!) of teaching is that it’s a rare educator that comes back in the fall still gunked-up. The summer lets you really clear your head, lets you drop all the baggage of the previous year — the gunk, bit by bit, just falls away.

We get to start the new year, every year, clean and fresh. Maybe not smiling and bright-eyed (we’re out of the habit of waking up early after all, but this is why coffee exists), but at least optimistic that the year ahead could be a good one.

Maybe we make some changes to the way we run things; maybe we don’t. Maybe we’ll have a magic combination of minds in our classes that makes every day teaching a joy; maybe we won’t.

But whatever the new year brings, we get a chance to start it un-gunked. Clear-headed. Renewed, reborn. Maybe even a little bit hopeful.

My first students will breach the doors in a little under an hour.

To those about to teach, I salute you.

See you on the other side.
