Professional and Social Settings

Over the past quarter-century, something fundamental has shifted in how Americans address one another. The decision to use last names has become increasingly rare, replaced by an immediate first-name basis that many find presumptuous. Walk into a doctor's office, meet a service provider, or introduce yourself to a colleague, and you'll likely hear your first name used within seconds of meeting. For many people raised with different standards of formality, this casual approach feels less like friendliness and more like a breach of etiquette.

Commander Adam Benson, a retired Naval officer, articulates what many feel but struggle to express: the erosion of formal address represents more than a simple change in linguistic habit. It reflects a broader shift in how we signal respect, maintain boundaries, and navigate social hierarchies in professional and casual settings alike.

The Social Function of Formal Address

The practice to use last names with honorifics serves several important social functions that immediate first-name basis interactions cannot replicate.

When you use last names, you create a respectful distance that allows relationships to develop naturally. Addressing someone as "Mr. Rodriguez," "Ms. Nelson," or "Dr. Chen" acknowledges that intimacy is earned rather than assumed. This distance isn't coldness; it's consideration. It recognizes that trust, familiarity, and affection grow over time through shared experiences and mutual regard.

To use last names also demonstrates basic respect for another person's station, accomplishments, and dignity. A judge who has spent decades serving the legal system, a professor who has earned advanced degrees, or simply an adult who deserves recognition as such — all merit the small courtesy of formal address until they invite otherwise.

Perhaps most importantly, the permission to use someone's first name becomes meaningful precisely because it isn't automatic. When we consistently use last names initially, the invitation to "Please, call me Jennifer" becomes a genuine gesture of warmth and welcome rather than a meaningless default.

When Society Stopped Using Last Names: A Generational Shift

Those who came of age in earlier decades learned a clear protocol: use last names and appropriate honorifics with adults and new acquaintances until invited to do otherwise. This wasn't stiffness or snobbery; it was simply how respect was demonstrated across generations and between people of different levels of familiarity.

Today's prevailing culture champions informality as a sign of openness and egalitarianism. The thinking goes that first names break down barriers, create friendly atmospheres, and prevent stuffy hierarchies from taking root. While genuine warmth certainly matters, informality imposed without choice isn't really egalitarian at all.

When the new contractor at your home launches immediately into calling you by your first name, or when a teenager addresses an adult they've just met as "Steve" rather than "Mr. Thompson," they may simply be oblivious to the preferences and comfort levels of others. The choice not to use last names becomes presumptuous when made unilaterally.

How to Use Last Names in Today's Informal Culture

How can those who prefer to use last names navigate today's first-name-default culture without seeming standoffish or outdated?

Commander Benson offers a practical example. While technically entitled to be addressed by his military rank, he accepts "Mr. Benson" as meeting the basic level of respect he seeks. This represents a reasonable compromise — maintaining formality without insisting on every ceremonial nicety.

When meeting new people, model the behavior you'd like to see. Introduce yourself with your full name and use last names for others until they indicate their preference. If someone immediately uses your first name, you might gently say, "I prefer Mr. Benson, at least until we know each other better." Most people, when clearly informed of a preference, will honor it.

In professional settings, defaulting to the practice to use last names remains especially appropriate. Business introductions, client relationships, and workplace hierarchies all benefit from the clarity and respect that formal address provides.

Teaching Children to Use Last Names

Another concern about immediate first-name usage involves children addressing adults. Unless an adult explicitly requests to be called by their first name, teaching children to use last names with appropriate titles instills several valuable lessons.

When children learn to use last names — "Mr. Lee," "Ms. Gupta," "Dr. Patterson" — they develop respect for elders, awareness that different contexts call for different behaviors, and understanding that not all relationships operate on the same level of familiarity. These aren't antiquated notions; they're building blocks of social intelligence that serve young people well throughout their lives.

Parents and educators who teach children to use last names when addressing adults give them a significant advantage in navigating formal settings, job interviews, academic environments, and professional relationships as they mature.

The Professional Advantage of Using Last Names

In business contexts, the decision to use last names can convey professionalism, respect, and appropriate boundaries. When meeting clients, potential employers, or senior colleagues for the first time, choosing to use last names demonstrates social awareness and respect for hierarchy and experience.

Many professionals find that when they use last names initially, they're taken more seriously and establish credibility more quickly. The transition to first names can then occur naturally as working relationships develop, making that shift meaningful rather than assumed.

Use Last Names to Preserve Choice and Respect

The practice to use last names need not represent stuffiness or social rigidity. At its best, formal address is a gift we give others: the acknowledgment that their comfort, dignity, and preferences matter. In a culture that increasingly defaults to immediate informality, maintaining the option to use last names preserves choice, respects boundaries, and allows the transition to first names to carry genuine meaning when it comes.

Whether you're navigating professional introductions, teaching children proper etiquette, or simply trying to show respect in daily interactions, the choice to use last names offers a time-tested tool for demonstrating consideration and building relationships on solid foundations of mutual respect.
