I am charming.

Not year-round. Catch me on a random Tuesday in February and there’s a decent chance I’m avoiding eye contact at the grocery store while pretending to study soup labels. But give me a wedding where one of my children is getting married, and I transform into a socially acceptable version of myself.

This weekend, the charm was dripping off me like sweat at an outdoor reception in Oklahoma.

Conversations? I could talk to anybody about anything. Politics, brisket temperatures, whether people under thirty still know how to parallel park—I’m in. People walked away convinced I was fully engaged the entire time. I probably was mostly engaged, but these varicose veins keep me from being fully ambistrous.

Yes, I looked it up. “Ambistrous” means being able to do something equally well sitting or standing. My brain can socialize indefinitely. My legs start filing formal complaints with management somewhere around minute thirty-seven. (Or was it those dress shoes?)

Normally I wait for people to find me. This weekend I was seeking them out, starting conversations on purpose, approaching strangers with something resembling confidence. This goes against every part of my being on most days—and, honestly, most years—of my life. But give me a wedding where I’m acquiring a son- or daughter-in-law and something in me rises to the occasion and says, “Today we will appear emotionally healthy.”

DIY wedding? Doesn’t shake me much. My wife wisely withholds enough of the plan to prevent me from offering what I call efficiency analysis and what others might call being difficult. If I don’t know the plan, I can’t optimize the plan. That’s marriage wisdom right there. And if my legs begin filing formal grievances, I wave the “functioning mutant” flag, find a couch, and cheer everybody on from a seated position.

Some people mistake this charm for pure sincerity. That’s not exactly right. It’s more like a carefully managed energy budget—burning today’s charm on credit from future me. The curtain can get thin. Those who know me know exactly which questions drop it.

But there’s a rare category of person who reverses the drain entirely. Someone who returns sass properly. Not cruelty—playful disrespect wrapped in affection. The kind that says, “I see you and I think you can handle this.” Conversational ping-pong. A way of saying, please don’t make me carry this alone.

One of the best surprises of the weekend was meeting Valerie. Not her real name, but it fits. In our family, she became known as the cougar. That’s the story as I received it, and I’m not fact-checking it now.

The origin goes back ten-plus years, when our son worked at the Chick-fil-A in the mall. Valerie was a mall walker who stopped afterward for a Dr Pepper. She wasn’t built for small talk. She’d ask whoever took her order something real—a question with follow-up potential. Our son passed her screening. If he didn’t know an answer, he’d look it up and have it ready next time. And knowing my son, there was some mild smart-mouth commentary included free of charge. All those years of me aggravating him had finally become an investment portfolio.

They stayed in touch. He visited her. She and her husband visited him during their three-year camper-living stretch. Phone calls when visits weren’t possible. This weekend, they came to his wedding.

What got me was how naturally she fit. She sparred with my other kids, my brother, and me like she’d known us for years. Nobody played it safe. Sometimes she’d get me with a good line and I’d fire one right back. You could see exactly why they kept up with each other—she’s the kind of person who refuses to let you be mediocre. If you weren’t going to show up as a real human, she’d have moved on to the next register.

But our son made an impression. A durable one. He earned that relationship by being fully himself, over and over, starting at a fast food counter before he was old enough to vote.

Forty-eight hours ago I had never met this woman. Now I’m a little jealous my son ended up with his own cougar grandma.

Me? Still charming, in short bursts. But I’m old enough to know I’m past the window for acquiring one of my own.

I’ll just keep the one I married.
