I’ve spent more than twenty years teaching high school students. In that time, I’ve encountered just about every teenage personality imaginable. The overachievers, the class clowns, the quiet observers, the students who question absolutely everything, and the ones who seem to consider lifting a pencil 
an unreasonable demand on their time. And somewhere along the way, I became a young adult fiction author.
When I started writing Consanguinity, the first book in my YA paranormal series, The Veilshard Chronicles, I had one advantage that I hadn’t really thought about. I spend my days surrounded by the very people I’m writing about. Of course, balancing teaching and writing isn’t always easy. I’ve written before about writing after a bad teaching day, when the classroom chaos follows you home and the blank page is waiting. But that same classroom chaos has taught me some valuable lessons about writing believable teenage characters.
Not that this makes writing teenagers easy. If anything, it means I know exactly how complicated they can be. After two decades in the classroom, I’ve learned a few things about teenagers that I wish more adults—and more authors—understood.
Teenagers Care More Than You Think
There’s a persistent misconception that teenagers are shallow, self-centered, and don’t care about anything beyond their phones, their friends, and whatever happens to be trending on TikTok. And yes, I’ve met teenagers who appear to fit that description. I’ve also met adults who fit it rather nicely, 
but that’s another blog post. Here’s what I’ve learned: Teenagers care. Sometimes they care so much that they don’t know what to do with all those feelings.
What they often lack isn’t compassion or empathy. It’s the emotional vocabulary, maturity, or confidence to explain what they’re experiencing. They don’t always know why they’re angry. They can’t necessarily explain why a friendship falling apart feels like the end of the world. They might be deeply concerned about something happening in their community but struggle to put those concerns into words. And sometimes, when they can’t find the words, their behavior does the talking.
As an author, that’s an important distinction. A believable teenage character doesn’t always understand their own emotions. They might say one thing, do another, and feel something entirely different. That’s not inconsistent characterization. That’s being sixteen.
Sometimes Caring Isn’t Cool
I’ve watched this happen in my classroom more times than I can count. A student gets genuinely involved in a discussion. They’re interested, engaged, asking questions, and sharing opinions. For a few glorious minutes, I think I’ve finally cracked the code and discovered the secret to getting teenagers excited about learning. Then they look around. Their friends are bored. Their classmates aren’t participating. Maybe someone rolls their eyes. And just like that, the enthusiasm disappears.
The student shrugs, leans back in their chair, and suddenly has absolutely nothing else to contribute. Did they stop caring about the subject in the span of thirty seconds? Of course not. They realized they were standing out. For teenagers, the desire to belong can be incredibly powerful. Sometimes it’s easier to pretend you don’t care than to risk being the only person in the room who does.
And this isn’t just something I’ve observed in my classroom. The American Psychological Association’s guide to adolescent development discusses the importance of peer relationships and identity development during adolescence. We tend to think about peer pressure in terms of drinking, drugs, or other risky behavior. But peer pressure can be much quieter than that. Sometimes it’s simply deciding not to raise your hand again.
When I’m writing teenage characters, I try to remember that the person they show the world isn’t necessarily the person they are inside. A character might be passionate about something in private but dismiss it in front of friends. They might want to defend someone but hesitate because they’re afraid of becoming the next target. Those contradictions don’t make teenagers shallow. They make them human.
The Same Teenager, Two Completely Different Conversations
Want to know what a teenager really thinks? Talk to them individually. I’d estimate that 90 percent of my students will happily have a one-on-one conversation with me. They’ll share opinions, ask questions, disagree with me, and occasionally surprise me with how deeply they’ve considered a subject. Put those same students in a classroom discussion, however, and suddenly nobody has anything to say.
I can ask a question, wait patiently, rephrase the question, offer examples, and practically perform interpretive dance at the front of the room. Nothing. Twenty-five teenagers staring at me as though I’ve just asked them to explain quantum physics in ancient Sumerian. But catch one of those students in the hallway or speak to them individually, and suddenly we can have a genuinely interesting conversation.
The difference isn’t necessarily intelligence or interest. It’s the audience. In a one-on-one conversation, they’re talking to their teacher. In a classroom discussion, they’re putting themselves on display in front of their peers. Every answer carries the possibility of being wrong, looking foolish, or attracting unwanted attention. That’s something I think about when developing characters.
A teenager who is outspoken with their closest friend might become painfully quiet in a group. Someone who challenges their parents constantly might struggle to disagree with a popular classmate. Confidence isn’t always a fixed personality trait. Sometimes it depends entirely on who’s watching.
Teenagers Are Walking Contradictions
One of my favorite things about teaching teenagers is how gloriously contradictory they can be. They want independence, but they still need reassurance. They insist they don’t care what anyone thinks, then spend twenty minutes worrying about something someone said. They can demonstrate 
remarkable compassion and maturity one moment and make an absolutely ridiculous decision the next. And sometimes they can explain a complicated historical or political issue with impressive insight but cannot remember to bring a pencil to class.
I couldn’t make this stuff up. Actually, I could. I’m a fiction writer. But you get the point. These contradictions are part of what makes teenagers interesting, both in real life and on the page. When adults write teenage characters, there’s sometimes a temptation to make them either miniature adults with extraordinary emotional intelligence or walking collections of bad decisions. Neither approach captures the whole picture.
Teenagers are developing their identities. They’re figuring out what they believe, who they trust, what matters to them, and where they fit into the world. Sometimes they get it right. Sometimes they get it spectacularly wrong. And sometimes they manage both before lunch.
Writing Believable Teenage Characters in Consanguinity
When I began writing Consanguinity, I wasn’t consciously thinking about all the lessons I’d learned from my students. I was thinking about Aisling, J.T., Eric, and Sabina—four teenagers whose lives become entangled with an ancient mystery, supernatural abilities, and a destiny none of them asked for. But the more I developed their stories, the more I realized how much my years in the classroom influenced the way I wrote them.
Aisling doesn’t suddenly become an emotionally mature adult simply because extraordinary things are happening around her. She’s still a teenager 
trying to make sense of her relationships, her feelings, and a world that is becoming increasingly difficult to understand. J.T. has his own history, his own fears, and his own ways of dealing with things he doesn’t necessarily know how to explain.
Eric and Sabina aren’t interchangeable supporting characters. They have their own personalities, insecurities, strengths, and ways of responding to the people around them. And like the students I’ve taught, they don’t always communicate perfectly. They misunderstand each other. They make assumptions. They hesitate. They react emotionally. Sometimes they make decisions that might leave an adult reader shaking their head. But that’s the point. They’re teenagers.
Being connected to an ancient supernatural mystery doesn’t magically give someone twenty years of life experience. If anything, extraordinary circumstances make ordinary teenage emotions even more complicated. And I think that’s what makes young adult fiction so interesting. The supernatural elements might create the danger, but the characters’ emotions are what make the danger matter.
Writing Believable Teenage Dialogue Is About More Than Slang
Here’s another thing I’ve learned: if you’re trying to make teenage dialogue believable by stuffing it with whatever slang happens to be popular this week, you’re probably going to regret it. For one thing, teenage slang changes faster than I can update my lesson plans. For another, teenagers don’t all 
speak the same way. The language they use with their friends isn’t necessarily the language they use with their teachers, their parents, or someone they’re interested in romantically.
And sometimes what they don’t say matters more than what they do. I’ve talked about this in my article on writing realistic dialogue, because authentic conversations are about much more than the words themselves. Teenagers communicate through sarcasm, humor, silence, exaggerated indifference, and the occasional eye roll that deserves its own Olympic event.
A character saying “Whatever” might mean they genuinely don’t care. Or it might mean they’re hurt, embarrassed, frightened, or trying desperately not to cry. The words are the same. The meaning depends on the person and the situation. That’s where believable dialogue comes from—not memorizing the latest slang, but understanding the emotions underneath the words.
The Most Important Lesson: Teenagers Are People
After more than twenty years in education, I still don’t claim to have teenagers completely figured out. I’m not sure anyone does. Some days, I leave school feeling as though I’ve made a genuine difference. Other days, I wonder whether anyone heard a single word I said. But I keep coming back to the same lesson.
Teenagers aren’t shallow simply because they struggle to express their feelings. They aren’t indifferent simply because they pretend not to care. And they aren’t all the same simply because they happen to be the same age. They’re individuals with complicated emotions, developing identities, fierce loyalties, insecurities, hopes, fears, and dreams. They want to be understood, even when they make understanding them incredibly difficult.
And that’s what I try to bring to my writing. When readers meet Aisling, J.T., Eric, and Sabina in The Veilshard Chronicles, I want them to see more than four teenagers caught up in a paranormal mystery. I want them to recognize something real. The awkwardness of first love. The fear of rejection. The desire to belong. The uncertainty of figuring out who you are and who you want to become.
Because whether you’re navigating the halls of a high school or discovering that your world isn’t quite what you thought it was, growing up is complicated. And sometimes the most extraordinary thing about a teenage character isn’t their supernatural abilities. It’s their humanity.
