Every generation carries a set of behaviors that feel completely normal from the inside but land differently when viewed from the outside. For Baby Boomers, born roughly between 1946 and 1964, many of those habits were shaped by a world of postwar stability, face-to-face culture, and very different social norms around privacy, work, and communication.
Boomers aren’t trying to make anyone uncomfortable. They’re doing what they’ve always done, what worked for decades, what still feels right. Meanwhile, younger generations experience full-body cringes over behaviors that seem perfectly reasonable to anyone born before 1965. Research involving over 1,700 participants found that Millennials and Baby Boomers express more animosity toward each other than toward any other generations, reflecting deep asymmetric concerns on both sides. Here are seven specific habits that sit at the center of that friction.
1. Calling Without Warning, Ever
The phone rings with no warning, no “is now a good time?” Just sudden sound demanding immediate attention. To Boomers, this is simply how phones work. To everyone else, it can feel like psychological warfare, the equivalent of someone pounding on your door at midnight. The assumption that a call is always welcome sits at the core of this tension.
Boomers tend to prefer phone calls over texts or emails, even for quick interactions, which younger generations find intrusive and inefficient. Millennials and Gen Z often view unsolicited phone calls as anxiety-inducing or disruptive, especially when a simple message would do. The expectation to “just pick up the phone” feels like a disregard for personal boundaries and modern communication preferences, especially in a world where people are constantly juggling multiple responsibilities.
2. Leaving Long, Detailed Voicemails
Voicemails feel like homework to younger people, obligations accumulating in digital purgatory. Boomers treat them as asynchronous conversations, complete with tone and warmth. They’re leaving friendly messages; recipients hear chores disguised as affection. The voicemail becomes a generational Rorschach test of what constitutes reasonable communication.
According to a 2025 study published in the International Journal of Research Publication and Reviews, Millennials and Generation Z strongly prefer instant messaging and text-based communication for quick, informal exchanges, while older generations like Baby Boomers tend to favor phone calls and voicemails. Even major carriers and tech advisors have shifted away from voicemail dependence, noting that younger users increasingly prefer asynchronous, text-based communication. A three-second text has effectively replaced the two-minute voicemail for most people under 40.
3. Dismissing Mental Health Conversations
Many Baby Boomers were raised to believe that mental health struggles should be kept private or ignored altogether, often viewing therapy as a last resort or sign of weakness. Younger generations, however, are actively working to destigmatize mental health by embracing therapy, discussing trauma, and prioritizing emotional well-being. Boomers’ reluctance to talk about feelings or seek help is viewed as not only outdated but also potentially harmful in a time when mental health awareness is seen as crucial.
For most Boomers, talking about stress, anxiety, or burnout in the workplace is still off-limits. They grew up in a society where you left your troubles at the door and toughed it out, no matter what. When Boomers label mental health conversations as oversharing or unprofessional, it can constitute a rejection of the values younger generations cherish. That disconnect stings especially hard when it comes from a parent or a manager.
4. Oversharing Personal or Medical Information in Public
This isn’t oversharing so much as a difference in privacy baselines. Boomers grew up when health was considered community property, and neighbors knew your prescriptions. Younger generations, raised on HIPAA and curated social media, treat medical information like nuclear codes. The collision creates visceral discomfort for everyone within earshot.
Baby Boomers often have a habit of using speakerphone in public, even when walking through a store or sitting in a café. While they may see it as a convenient way to communicate, younger generations find it intrusive and inconsiderate. Combined with candid health conversations held at full volume, the sense of unwanted intimacy in shared spaces is a recurring sore spot for younger people.
5. Romanticizing the Past While Dismissing the Present
Boomers often wax nostalgic about a supposedly simpler, better past, usually the 1950s, 60s, or 70s, without acknowledging the social and systemic inequalities that existed during those times. Younger people view this rose-colored perspective as dismissive of the progress made in areas like civil rights, gender equality, and LGBTQ+ acceptance. To them, glorifying the past often comes across as willfully ignoring the hardships others endured and undermines efforts to build a more inclusive future.
For many Baby Boomers, traditional family structures, gender roles, and societal expectations were often rigid and well-defined. Over time, those norms have evolved to be more inclusive and diverse. Today’s world values fluidity and flexibility in relationships, gender identity, and career paths. Baby Boomers who cling to outdated social norms risk alienating younger generations, who prioritize equality, inclusivity, and individuality.
6. Unsolicited Comments on Appearance or Choices
Observations like “You’d be prettier smiling,” “Interesting hair color choice,” and “Too young for those tattoos” are delivered like gifts but received like grenades. Boomers think it’s just conversation. Everyone else hears boundary violations. The generational divide here isn’t about intent, it’s about whether commenting on someone’s body or aesthetic choices is even an appropriate social act.
Many Boomers seem to really enjoy dress codes and strict definitions of what kind of clothing is acceptable for whom, meaning anything from enforcing jackets required at a restaurant to more extreme examples tied to appearance-based judgments. Younger generations tend not to care as much about what other people are wearing. The discomfort comes not from criticism itself but from the casual entitlement to offer it at all.
7. Demanding Old-School Workplace Loyalty and Rigid Hours
For decades, Baby Boomers championed traditional, rigid work environments that emphasized long hours in the office, face-to-face meetings, and fixed schedules. The modern workforce, however, thrives on flexibility, remote work, and results-driven performance. The pandemic accelerated this shift, and many younger generations now prefer jobs that offer autonomy, work-life balance, and the ability to work from home or on the go.
A 2022 EY US Generation Survey found that Baby Boomers are not overly interested in their company’s culture, with fewer than roughly three in ten saying that company culture had an impact on their remaining at their current organization. On the other side of the spectrum, roughly four in ten Gen Z and Millennial respondents highlighted that culture plays a big part in their desire to stay with their employer. When Boomers frame long office hours as dedication and flexibility requests as laziness, younger workers don’t just feel misunderstood. They start updating their resumes.
None of these habits exist in a vacuum, and it’s worth noting that generational narratives, while widespread, have little basis in hard science. There is no scientific evidence that Millennials are lazier or Baby Boomers more stubborn. After reviewing more than 30 years of academic research, the National Academies of Sciences concluded that generational boundaries are arbitrary and that alleged generational differences, when not entirely made-up, reflect mostly situational and life-stage differences.
Still, the discomfort is real, even if the labels are imperfect. What matters more than assigning blame is recognizing that two people can both be acting in good faith and still make each other genuinely uncomfortable. That gap, more than anything, is worth closing.
