High school is hard enough when everything at home is going right.

Now imagine walking through those doors when you don’t really know where home is anymore.

I saw that reality recently in the face of a student. I won’t tell you the student’s name. I won’t tell you the grade, the circumstances, or anything else that could identify this young person. Some stories belong to students, not to teachers. But I can tell you what I saw.

I saw a teenager who looked shell-shocked.

Here was a young person being placed into a high school while dealing with foster care—expected to navigate new hallways, new teachers, new classmates and all the ordinary pressures of being a teenager while carrying something extraordinarily heavy. And then we expect that student to learn.

Think about that for a moment.

High school can feel terrifying even for a student who knows exactly where they’re going when the final bell rings. Teenagers worry about fitting in. They worry about grades, friendships, relationships, clothes, acne, lunch tables and whether somebody is going to laugh when they answer a question incorrectly. Now add uncertainty about where you’re going to sleep.

I’ve worked with students facing difficult circumstances before. I’ve encountered poverty, unstable homes and young people carrying responsibilities far beyond their years. I thought I understood it.

But there are moments in teaching that humble you. This was one of them.

And foster care is only part of what educators see. There are students experiencing homelessness. Students moving between relatives, friends, temporary housing and shelters. Students who don’t have the supplies everyone assumes a teenager has. Students who arrive exhausted because whatever happened the night before didn’t stop simply because school started the next morning.

Sometimes the student sitting next to your child may be carrying a life your child knows absolutely nothing about. Neither may the teacher.

That’s important to remember.

The student without a pencil isn’t necessarily irresponsible. The student who puts their head down may not be lazy. The student who didn’t finish the assignment may have had something more urgent to worry about than homework.

That doesn’t mean educators stop having expectations. Quite the opposite. Our students deserve to be challenged. They deserve Shakespeare and great novels and difficult questions. They deserve teachers who believe they are capable of more than simply surviving their circumstances.

But compassion and expectations can occupy the same classroom. Sometimes compassion is simply recognizing how much effort it took for a student to make it through the classroom door.

As teachers, we spend enormous amounts of time thinking about what we’re going to teach. We build lessons. We write objectives. We create assessments. We analyze data. We worry about whether students are reading on grade level and whether they are prepared for what comes next.

All of that matters.

But there are days when the most important thing in the room isn’t written on the lesson plan.

It’s noticing.

Noticing the student who suddenly got quiet. Noticing the student wearing the same clothes. Noticing the student who doesn’t have what everyone else has. Noticing the student whose whole world may have changed before they ever walked into your classroom.

And then doing something educators sometimes forget we’re allowed to do:

Being human.

I cannot fix every problem my students face. No teacher can. I cannot promise a teenager that life will suddenly become fair.

But I can make one promise.

For the time they are in my classroom, they have a place where someone expects them to succeed, notices when they’re struggling and believes their circumstances do not determine the rest of their story.

Maybe that’s why that student’s face has stayed with me. I keep thinking about how frightening it must have been to walk into an unfamiliar high school carrying all of that uncertainty.

And yet the student walked in.

That’s the part I don’t want us to miss.

They walked in.

They sat down.

They came to learn.

Tomorrow morning, millions of students will do the same thing. Most of us will never know everything they carried with them through those doors.

Maybe we don’t need to know every detail. Maybe we just need to remember that every desk has a story sitting behind it.

And sometimes, simply making it to that desk is an act of courage.
