Pet Peeves Boomers Have With Millennials and Gen Z’s Annoying Habits

Generational differences often lead to frustration, but understanding can bridge the gap.

Every generation has quirks that rub others the wrong way, and Millennials and Gen Z are no exception. Seniors aged 60+ often find themselves puzzled or annoyed by behaviors that seem second nature to younger generations. From smartphone obsessions to shifts in traditional values, these differences can lead to misunderstandings. Here are 13 common pet peeves that reveal the unique friction between these generations—and maybe even some room for mutual understanding.

1. Overusing technology during personal interactions

Seniors often feel sidelined when Millennials and Gen Z focus on their phones or gadgets during face-to-face conversations. This behavior can come across as disrespectful or dismissive, especially at family gatherings or social events. For seniors, undivided attention is a sign of respect and genuine interest. Younger generations may see multitasking on devices as second nature, but this habit can erode the personal connections seniors cherish. Acknowledging the value of in-person presence could make interactions more meaningful.

2. Forgetting to say “please” and “thank you”

Basic courtesies like saying “please” and “thank you” matter deeply to seniors who grew up in an era that emphasized politeness. When younger people skip these phrases, it can feel like a lack of respect or gratitude. Millennials and Gen Z often communicate more casually, which can unintentionally offend. While it’s likely not meant to be rude, reintroducing these small acts of kindness could strengthen relationships and demonstrate respect across generations.

3. Wanting instant gratification in every aspect of life

Millennials and Gen Z have grown up in a fast-paced, tech-driven world, where answers, deliveries, and results often come immediately. Seniors, however, value patience and the idea that good things come to those who wait. Younger generations’ impatience can seem entitled or unrealistic to seniors who have spent years working toward long-term goals. Understanding each other’s timelines and the pressures that shape them might foster greater empathy on both sides.

4. Viewing traditional work ethic as outdated

Seniors often take pride in their history of long-term careers and hard work, sometimes spanning decades with one employer. They may feel frustrated when Millennials and Gen Z prioritize work-life balance or pursue side hustles over conventional full-time jobs. To older generations, this approach might appear as a lack of dedication. However, younger people see it as adapting to a changing world. Open conversations about work values could help bridge this divide.

5. Staying financially dependent on parents into adulthood

Seniors who grew up in an era of early independence often struggle to understand why Millennials and Gen Z might live with parents or rely on financial support well into their late 20s or 30s. Rising costs of living, student loan debt, and a volatile job market play significant roles in these choices, but they can still cause frustration. Acknowledging these economic differences while appreciating younger generations’ resilience could reduce some of the judgment.

6. Using excessive slang and internet abbreviations

Millennials and Gen Z often sprinkle their conversations with slang, acronyms, and memes, leaving seniors feeling out of the loop. Terms like “slay,” “FOMO,” or “low-key” may seem silly or confusing, while abbreviations like “LOL” or “BRB” can feel impersonal. Seniors might interpret this language as a lack of clarity or seriousness. Efforts to include everyone in the conversation, even when using modern lingo, could help ease this frustration.

7. Avoiding face-to-face communication

Seniors often value in-person conversations, seeing them as the best way to foster genuine relationships. Millennials and Gen Z, on the other hand, often prefer texting, video calls, or social media interactions, which can feel impersonal or superficial to older generations. For seniors, this reliance on digital communication might seem like a reluctance to engage meaningfully. Bridging the gap could involve a mix of both worlds—embracing technology while carving out time for in-person connections.

8. Dressing too casually in professional settings

The casual dress habits of Millennials and Gen Z can puzzle seniors, who associate professional attire with respect and formality. Jeans, sneakers, or hoodies at work or events might seem inappropriate to seniors who grew up in an era where dressing up was a sign of effort and decorum. While younger generations value comfort and personal expression, acknowledging the importance of appearances in certain contexts could help build mutual respect.

9. Disregarding traditional skills like cooking or repairs

Seniors often take pride in practical skills like cooking from scratch, sewing, or repairing household items, which they see as essential life tools. Millennials and Gen Z, however, tend to rely on apps, services, or convenience products to get these tasks done. This dependence can feel like a lack of self-sufficiency to older generations. Encouraging younger people to embrace these traditional skills could foster a sense of accomplishment and intergenerational learning.

10. Being overly sensitive to opinions and criticism

Seniors sometimes perceive Millennials and Gen Z as too quick to take offense, especially when discussing sensitive topics. Terms like “triggered” or the emphasis on political correctness can make older generations feel as though they need to walk on eggshells. Seniors value open dialogue, even if it includes opposing views. Finding a balance between respectful communication and embracing diverse opinions might help bridge this cultural gap.

11. Prioritizing social media over real-life experiences

For seniors, the constant scrolling and sharing on social media by Millennials and Gen Z can seem like a distraction from meaningful real-life moments. The pressure to capture the “perfect” photo or gain likes can feel superficial to those who prioritize living in the moment. Seniors may appreciate younger generations putting their devices down to focus on deeper connections and memories, showing that the present matters more than the post.

12. Disregarding the importance of history and tradition

Millennials and Gen Z are often seen as dismissing historical events, traditions, or cultural norms that seniors hold dear. Whether it’s an offhand comment about history being irrelevant or a reluctance to participate in family traditions, these actions can feel disrespectful. Seniors appreciate when younger generations take an interest in the past and honor customs. Sharing these traditions and their significance could help younger people see their value.

13. Treating loyalty to employers as outdated

Many seniors spent decades working for the same employer, building a sense of stability and pride in loyalty. Millennials and Gen Z, however, often view job-hopping or freelancing as necessary for career growth or fulfillment. To seniors, this can come across as a lack of dedication or an unwillingness to stick through challenges. Younger generations could benefit from understanding the perspective of stability while also explaining the pressures and opportunities of today’s job market.
