When Gen Z doesn’t recognize your entire childhood, you realize time moves faster than you thought…

Last week, Sarah’s younger cousin asked me what a “CD” was after seeing my old collection in storage. I had to pause mid-sentence because suddenly, I felt like I’d aged twenty years.

According to research, millennials are one of the most nostalgic generations, with 14% of us preferring to think about the past rather than the future. Honestly? I get it.

We’re caught in this weird time warp, straddling the analog and digital worlds, and now Gen Z is looking at our childhood like it’s ancient history.

Here are seven things that instantly make us feel ancient, and yeah, a little emotional too.

1) When Gen Z doesn’t know what a Blockbuster was

Remember Friday nights spent wandering the aisles of Blockbuster, debating which movie to rent, knowing you’d have to rewind it before returning it?

Now try explaining that entire ritual to someone who’s never known anything but Netflix.

Marcus and I were talking about this the other night, and he brought up how we used to plan our entire weekend around new releases. You’d call ahead to see if they had copies available. You’d drive there hoping they weren’t all rented out.

The whole experience was an event.

Today’s kids have thousands of movies at their fingertips, no late fees, no rewinding. But honestly? They’re missing out on that specific thrill of finally getting your hands on the movie everyone was talking about.

2) Realizing people born after 9/11 are adults now

This one hits different.

I was in middle school when the towers fell. It’s one of those memories seared into your brain—the kind where you remember exactly where you were, what you were doing, how the room felt.

But now? Kids in high school today weren’t even born yet. For them, 9/11 is just a chapter in their history textbook, something that happened before they existed.

One of the most defining moments of our generation is ancient history to theirs.

That realization hits hard.

3) When your music becomes “throwback” playlists

Sarah sent me a Spotify playlist the other day titled “2000s Throwbacks” and I genuinely got offended.

Throwback? We’re talking about music from when I was in high school. That was, like, yesterday in my mind.

Except it wasn’t.

The early 2000s were twenty-plus years ago. Fall Out Boy, Paramore, and My Chemical Romance, the bands that soundtracked my teenage angst, are now considered “vintage” or “retro.”

Gen Z is discovering these songs for the first time on TikTok, treating them like archaeological finds, while we’re over here thinking “Wait, this was literally playing at my prom.”

Studies show that younger generations often prefer music from decades they never experienced, which explains why 90s and 2000s music is having such a revival.

But for us? It’s not a revival. It’s just… our music.

4) Having to explain pre-smartphone life

Picture this: you’re trying to meet up with friends, but nobody has a cell phone. You have to actually pick a time and place, show up, and hope everyone else does too.

If someone’s running late? You just wait. No text updates, no “omw” messages, nothing.

Emma asked me the other day how we ever coordinated anything without group chats, and I realized explaining it made me sound like I grew up in the Stone Age.

MapQuest printouts. Asking for directions at gas stations. Getting genuinely lost with no GPS to save you.

These aren’t horror stories. This was just normal life.

But to anyone under 25, it sounds absolutely unthinkable. And honestly? It kind of was.

5) When classic Disney movies are older than your coworkers

The Lion King came out in 1994. Toy Story in 1995. These are foundational movies for millennials, the kind that shaped our childhoods.

But here’s the thing: some of my coworkers weren’t even born yet when these came out.

I was chatting with someone at work recently who mentioned she’s 23, and I did the math in my head. She was born after The Matrix, after Fight Club, after all those movies we consider modern classics.

It’s one thing to feel old when movies celebrate big anniversaries. It’s another thing entirely when you realize the films that defined your generation are now hitting 30-year milestones.

Suddenly you’re the “old guy” at the office who remembers when these came out in theaters.

6) Being called “sir” or “ma’am” by teenagers

This is the one that really gets you.

You’re at a coffee shop, and a teenager behind the counter says “Here you go, sir” and hands you your order.

Sir?

I mean, I know I have a baby face. I’ve been getting carded since forever. But apparently, to actual teenagers, I look like a full-grown adult worthy of “sir” status.

Katie, my younger sister, laughed when I told her this happened to me. But then she admitted a high schooler called her “ma’am” at Target last month and she had an existential crisis in the parking lot.

We’re not old. We’re in our thirties. But to Gen Z? We’re basically the establishment.

7) Watching your childhood get turned into “vintage” fashion

Low-rise jeans are back. Butterfly clips are everywhere. Gen Z is raiding thrift stores for the exact clothes we donated years ago because they were “so out of style.”

The thing is, they’re not wearing them ironically. They genuinely think this stuff is cool and new.

Meanwhile, I’m watching cargo pants make a comeback and having flashbacks to middle school. These trends aren’t nostalgic for them because they never experienced them the first time around.

Fashion researchers note that Y2K fashion references appeared in over 73% of Gen Z-targeted brand campaigns in 2025. They’re calling it “vintage” and “retro,” terms that make us feel about a hundred years old.

Because when the fashion choices you made as an actual teenager become costume pieces for the next generation? That’s when you know time has officially moved on without asking permission.

Rounding things off

Feeling old is weird, disorienting, and sometimes a little sad.

We’re at this strange crossroads where we’re young enough to relate to Gen Z culture but old enough that our childhood is incomprehensible to them. We remember dial-up internet and mixtapes and having to be home by a certain time because that’s when your favorite show aired.

But here’s the thing: every generation goes through this. Someday, Gen Z will be the ones explaining TikTok and Fortnite to confused Gen Alpha kids who can’t imagine life without brain-computer interfaces or whatever comes next.

Time keeps moving. Generations keep shifting. And all we can do is embrace the fact that yeah, we’re getting older, but at least we got to experience some genuinely cool stuff along the way.

Plus, someone has to stick around to explain what a VHS tape was.
