I just came back from Korea.
Our tour guide was exceptional. And somewhere between the royal palace in Seoul and a bowl of seaweed soup in Busan, I realised why.
She wasn't just showing us Korea. She was representing it.
When we visited Gyeongbokgung Palace, she paused at one particular spot and mentioned, almost in passing, that this was where the last Korean queen was murdered by the Japanese.
I don't think many people in the group caught it.
But I did. Because underneath that casual sentence, I could hear something real. A quiet grief. A pride that had been wounded and never fully healed.
She had probably said those words dozens of times to dozens of tour groups. But they didn't sound rehearsed. They sounded personal.
That's when it struck me.
To her, Korea was not just a collection of facts and attractions to be delivered efficiently and on schedule. Korea was her story. Her identity. Her pride.
And because of that — Korea became real to me too.
I started thinking about Mathematics.
As teachers, we are tour guides to our subject.
We represent Mathematics to our students — perhaps for the first time, perhaps at a moment that will shape how they feel about it for the rest of their lives.
If we are dismissive of Math — if we treat it as a collection of formulas to be memorised and regurgitated — that is the vibe our students will absorb.
If we are genuinely in love with what Math reveals about the world — about logic, about patterns, about the way problems yield to careful thinking — that love will find its way into the room.
Students feel the difference. Even when they can't name it.
Our tour guide never assumed we knew things.
Even facts she had shared hundreds of times, she delivered as if we were hearing them for the first time — because we were.
She didn't say "Daegu is an industrial town" and move on. She brought us back to the 1960s, when Korea's GDP per capita was six US dollars. She told us about presidents who shaped the nation's destiny. She made us feel the weight of how far Korea had come — so that what we were seeing wasn't just a city, but a story of transformation.
How often do we do that in Math? How often do we share the story behind a formula — the brilliant, sometimes eccentric minds who discovered it, the historical moment it emerged from, the way it changed what was possible?
Math has all of this. We just rarely tell it.
Our tour guide also paid attention to us as individuals.
She noticed things. She commented on how a mother and son interacted. She said something kind about how a brother looked after his sister. She saw us — not as headcounts, but as people.
The best teachers do the same. They notice. They remember. They make students feel seen in a subject that can easily make them feel invisible.
She shared her own life too.
She told us about making seaweed soup on her birthday when nobody remembered. About her mother-in-law decorating the walls with printed photos from past trips. About the time she bought expensive beef to cook for herself, only to have the moment quietly ruined.
I used to think that sharing personal stories in a lesson was unprofessional. I'm here to teach Math — why talk about myself?
But watching her, I understood something.
When she shared her life, two things happened.
First, she became a real person to us — not just a voice delivering information, but a human being with her own joys and disappointments. And that made everything she said more worth listening to.
Second, her stories made dry facts come alive. The reason beef is expensive in Korea landed differently when it was attached to a birthday she spent alone with a pot she had saved up to cook.
That is exactly what a good teacher does. We are not just delivering content. We are making our subject human. We are being human, in front of people who are learning what it means to be human.
There is one more thing I noticed about our tour guide — and it is the thing I needed most to hear.
She has led tour groups through the same streets, the same palaces, the same restaurants, probably hundreds of times. Everything is familiar to her. Nothing is new.
I know that feeling.
After eighteen years of teaching the same syllabus, I sometimes catch myself getting impatient with the simplicity of what I'm explaining. I have taught this concept so many times. It feels trivial to me now. And that impatience, if I am not careful, leaks into the lesson.
The irony is this: the more familiar a tour guide is with the destination, the better equipped she is to guide — and yet the more bored she risks becoming.
The antidote lies in where you place your attention.
The destination is the constant. The people are the variable.
Our tour guide understood this. She didn't just lead us through Korea — she paid attention to us. She noticed the dynamics between family members. She made comments that showed she had been watching, quietly, all along.
And I think she appreciated the 缘分 — the particular fate that brought this specific group of strangers together, with her, at this moment in time. Something that would never be exactly repeated.
That is the reminder I brought home.
As teachers, we are not here to teach the subject. We are here to teach the person.
The Math stays the same. The student in front of you — never.
