The Day the Bank Changed

It’s been a long time since I last wrote on My blog & Medium. Somewhere between work, deadlines, and telling myself “I’ll write again next week”, writing quietly disappeared.

But today, a small trip to the bank made me want to write again.

I went to the bank with my boy.

The mission sounded noble: teach him how to add money to his savings account. A proper life lesson. Financial responsibility. Parenting achievement unlocked.

In my head, I already knew how this would go.

Fill deposit slip. Hand money to teller. Receive stamped receipt. Go home feeling like a responsible adult.

Simple.

The Confident Tech Guy Walks In

I walked into the bank feeling confident.

I work in tech. I deal with systems, automation, APIs, servers, AI, all the modern stuff.

Surely depositing money wouldn’t surprise me.

When I walked in, my instinct immediately kicked in.

I went straight to the table near the entrance, scanning for the familiar deposit slips, you know, the small papers we used to fill with careful handwriting and questionable pen quality.

Except… I couldn’t find any.

While I was still looking around like someone searching for a relic from the past, the security guard approached and asked what I wanted to do.

“Deposit money,” I said confidently.

He simply pointed me toward the teller.

No forms. No paperwork preparation phase. Just… go directly to the counter.

The teller asked for the account number.

She took the cash.

She counted it, confirmed the amount, then calmly said:

“Please approve from your mobile banking app sir.”

I froze for a second.

Approve… from my phone?

I opened the app, and there it was, a transaction approval request already waiting.

The teller wasn’t waiting for my signature.

She was waiting for my tap.

At that exact moment, I realized something slightly embarrassing:

I came thinking I understood technology… but technology had quietly moved ahead without informing me.

When You Think You’re Tech-Savvy

I always considered myself reasonably tech-aware.

I follow new frameworks. I experiment with infrastructure. I read about AI breakthroughs before they become mainstream.

Yet somehow, banking workflows evolved in a direction I never noticed.

Turns out, technology doesn’t only advance where we look.

While I was learning about cloud systems and inference models, banks were redesigning everyday human processes.

And life gently reminded me:

Being “tech-savvy” doesn’t mean knowing everything. It just means you’re used to learning new things.

The Unexpected Cost of Teaching

After finishing the deposit, we walked back to the parking area.

Parking fee: Rp4.000.

And suddenly I had a funny realization.

Technically… saving money today cost me money.

I paid parking, spent time, and used fuel. All to deposit cash that I could have transferred instantly from my phone while sitting at home.

Financial efficiency: questionable.

Parenting experience: priceless.

Because the goal wasn’t optimization.

It was experience.

My son saw how banks work. He saw money being handled. He experienced something physical, not just digital numbers moving on a screen.

And that matters.

Life Is Continuous Learning

I went there thinking I was teaching my son.

Instead, both of us learned something.

He learned how saving works.

I learned that no matter how much experience we accumulate, the world keeps evolving faster than our assumptions.

Life isn’t about reaching a point where you finally “know enough.”

It’s about staying curious enough to keep learning.

Sometimes from books. Sometimes from work. Sometimes from a bank teller asking you to approve a transaction on your phone.

Moral of the Story

Next time?

I’ll probably just transfer the money to his account.

Cheaper. Faster. No parking fee.

But I regret nothing.

Because sometimes a small financial loss buys something more valuable:

A shared moment. A new lesson. A reminder that growth never stops.

And maybe that’s the real savings account we’re all building, experience compounded over time.
