Ever wonder why your well-meaning text message came across as cold? Or why that polite phrase you learned growing up suddenly makes younger folks uncomfortable?

Last month, my 14-year-old granddaughter showed me a text I’d sent her. “Thanks for letting me know.” That was it. She asked if I was mad at her. Mad? I was being polite! But apparently, ending a text with a period these days is the digital equivalent of slamming a door. Who knew?

This got me thinking about all the ways different generations interpret courtesy. What my generation considers basic manners, Gen Z often reads as subtle hostility. After spending time with my five grandchildren and watching them navigate the world so differently than I did, I’ve noticed some fascinating patterns.

As a side note, the workplace has become a particularly interesting battleground for these misunderstandings. During my 35 years in insurance, certain behaviors were just expected. Now? Those same behaviors can torpedo relationships faster than you can say “OK Boomer.”

1. Ending texts with periods

Remember when we learned that every sentence needs proper punctuation? Well, throw that rule out the window when texting anyone under 30.

To us, “Sure.” means exactly what it says. To Gen Z, that period might as well be a knife. They read it as curt, annoyed, or dismissive. Meanwhile, “Sure!” or just “Sure” feels friendly and open.

I learned this the hard way after weeks of confusing exchanges with my younger grandkids. They’d ask to come over, I’d respond “That sounds great.” and then crickets. Later, their parents would mention the kids thought I didn’t really want them to visit.

The thing is, Gen Z grew up with texting as their primary communication. They’ve developed their own subtle rules and signals that we’re just catching up to. A period in a text isn’t grammar; it’s tone. And that tone says, “This conversation is over, and I’m not happy about it.”

2. Using “No problem” instead of “You’re welcome”

This one drives both generations crazy, just in opposite directions.

When someone thanks me, I say “You’re welcome.” It acknowledges their gratitude and closes the loop nicely. But when Gen Z hears this, many interpret it as passive-aggressive, like you’re saying, “Yes, I did do you a favor, and you better appreciate it.”

They prefer “No problem” or “Of course!” which to them communicates that helping was effortless and expected. But when I hear “No problem,” part of me thinks, “Well, why would it be a problem? I just said thank you!”

It’s a classic case of different baseline assumptions. My generation assumes helping might be an inconvenience worth acknowledging. Gen Z assumes helping should be the default, not worth making a fuss over.

3. CCing the boss on emails

Want to instantly make a Gen Z colleague suspicious? CC their manager on a routine email exchange.

In my office days, copying supervisors was standard practice. It kept everyone in the loop, created paper trails, and showed you were being transparent. These days? It’s seen as tattling or trying to get someone in trouble.

A friend recently told me about her daughter’s first job experience. A boomer colleague kept CCing the manager on every email exchange about a project they were collaborating on. The daughter was convinced this colleague was documenting her mistakes to get her fired. In reality, the colleague was just following what she thought was professional protocol.

The shift makes sense when you think about it. Gen Z values psychological safety and collaborative environments. To them, involving the boss unnecessarily feels like escalation, not transparency.

4. Compliment sandwiches in feedback

You know the formula: start with something positive, deliver the criticism, end with another positive. “Your presentation was engaging! However, the data was incorrect on slides 3 through 7. But I loved your enthusiasm!”

We were taught this was the kind way to deliver feedback. It softens the blow, right?

Gen Z sees right through it and finds it patronizing. They know criticism is coming the moment you start with unexpected praise. The whole ritual feels fake and makes them question every compliment you give.

They prefer direct, constructive feedback without the sugar coating. “Hey, slides 3 through 7 have incorrect data. Here’s the right info.” Clear, helpful, done.

My youngest daughter, who manages a team of twenty-somethings, had to completely rewire her feedback style. She says her team responds much better to straightforward conversations than diplomatic dances.

5. Phone calls without warning

Here’s something that would have been absurd to explain to my parents: calling someone on the phone, without texting first, is now considered rude.

When I was working, if you needed something, you picked up the phone. It was efficient, personal, and showed initiative. Now? An unexpected phone call sends Gen Z into a panic. They assume something terrible has happened or you’re about to deliver bad news.

The protocol now is to text, “Hey, can I call you about X?” or “Got time for a quick call?” This gives them time to mentally prepare, find a quiet space, or suggest an alternative if they’re not in a good headspace for a conversation.

I’ll admit, this one took me the longest to understand. But after watching my grandkids literally freeze when their phone rings unexpectedly, I get it. They’ve grown up with the ability to control when and how they communicate. A surprise phone call feels like an ambush, even when it’s meant as a friendly check-in.

Final thoughts

These generational differences aren’t about right or wrong. They’re about different contexts and experiences shaping how we interpret social cues.

My generation learned courtesy in face-to-face interactions, where tone of voice and body language filled in the gaps. Gen Z learned it through screens, where every punctuation mark carries weight and availability is something you control, not surrender.

The solution isn’t picking sides but being aware and adapting when we can. I still catch myself adding periods to texts, but now I know to add an emoji when messaging my grandkids. And maybe, just maybe, they’ll forgive me when I occasionally forget to text before calling.
