The Retired Engineer Who Ruined My Adult Class (And Taught Me How to Run One)

His name was Gary. Retired mechanical engineer, front row, arms crossed, and by week two of a study on Romans he had derailed the discussion three separate times to explain why my metaphor about grace didn't hold up logically. He wasn't wrong, exactly. That was the problem.

I've taught adults across three churches now, and I'll tell you the thing nobody warns you about: a room of grown-ups is harder than a room of second graders. Not louder. Harder. Kids check out visibly. They fidget, they crawl under tables, they tell you they're bored. Adults just go quiet and polite and mentally somewhere else, and you don't find out you lost them until the room stays silent after you ask a question you thought was easy.

With Gary, the silence was different. Everyone else stopped talking because they figured he'd answer first, and he'd answer better, and why bother. I watched a class of fourteen shrink down to a two-person conversation between me and one confident retiree while twelve other adults studied their coffee. Took me about a month to even notice it was happening.

Here's what I got wrong. I thought the problem was Gary. I spent weeks trying to manage him, redirect him, gently cut him off. None of it worked, and honestly it made the tension worse because now the whole room could feel me steering around one guy.

The fix wasn't managing the loud person. It was changing the shape of the question.

Stop asking questions that have an answer

Most adult Sunday school lessons are built on questions that reward the person who already knows the most. "What does Paul mean here?" is an invitation for the Gary in your room to deliver a lecture. There's a right answer, he's pretty sure he has it, and everyone else defers.

So I stopped asking questions with answers. I started asking questions that only the person could answer for themselves. Not "what does this passage mean" but "where have you actually seen this play out, or fail to?" Nobody can out-expert you on your own experience. Gary couldn't correct someone's story about their own marriage or their own doubt. He could only listen to it. And a funny thing happened. He got quieter, and then he got interesting, because when he did talk it was about his life instead of his knowledge.

The shift sounds small. In the room it's enormous. You go from a class where one person performs and everyone grades him, to a class where the expertise is distributed because everybody is the world's leading authority on their own life. That's the whole trick with adults. They have decades of material. Most curriculum just never asks for it.

What actually changed in the room

I'm not going to pretend this fixed everything, because it didn't. Some weeks the conversation still died. Some people just don't want to talk, and after years of doing this I've made peace with the fact that a quiet adult isn't necessarily a disengaged one. I have zero reliable way to tell the difference, and anyone who says they can is guessing.

But here's what shifted, concretely:

• Participation spread out.
• The average number of people who spoke in a given hour went from about four to somewhere near ten, and it stayed there for months, which for a class of fourteen adults is the difference between a discussion and a monologue with witnesses.
• Gary started staying after class to talk to people instead of cornering me to debate a footnote, which I did not see coming and still don't fully understand, except that maybe he'd been talking so much because nobody had ever actually asked him anything real.

A caveat, because I'd be lying otherwise. This works when your class is under twenty or so and people roughly know each other. In a big adult class where folks are still strangers, experience questions land flat because nobody wants to hand a personal story to a room of people they don't know yet. For those rooms you need weeks of low-stakes warmup first, and I don't have a clean formula for how many. Depends on the people. It always depends on the people.

If I could go back and tell myself one thing before that Romans study, it'd be this: the loud person in your adult class is almost never the actual problem. The problem is that you built a lesson that has a winner. Take the winner out of the question, and the room changes on its own.

Gary, for what it's worth, sent me a note when I moved churches. Said it was the first class in years where he felt like he learned something instead of proving something. I've thought about that line more than I've thought about most of the lessons I actually prepared.
