The first rule when it comes to taking a side dish to a gathering of friends and family is simple.

Stick to what you know.

By the way, does a person “take” or “bring” something? As an old English major, I should know that, but it’s one of those either/or situations that often confounds me.

Did I decide to take potato salad ... or bring it?

That’s actually beside the point.

Why did I decide to make potato salad at all?

After all, it’s been my wife’s specialty since I met her and, believe me, she’s a master at it.

Me?

I’m better with things like a broccoli and bleu cheese casserole.

Or an antipasto salad.

Or shrimp with mushrooms and wild rice.

But potato salad?

Not in my wheelhouse, which is why it was so unusual for me to step outside my comfort zone last weekend.

The occasion was a music festival in a waterfront town called Beaufort and a former colleague of mine has a beach house not too far from that town. He’d invited us -- which was very cool -- and run down the menu of what he was planning to serve.

Hamburgers.

Hot dogs.

And, as a wild card, live crawfish ordered from Louisiana.

“They’re like little lobsters,” he said. “Steam ‘em, season ‘em and enjoy.”

“More like palmetto bugs,” my wife said, when I brought her up to date. “Except they’re red.”

She had a point.

I’d seen folks order a mess of crawfish and they’re, let’s say, an acquired taste.

But that aside, I believed my wife’s potato salad -- a big hit whenever she serves it -- would be a perfect accompaniment.

Imagine my surprise when she looked at me and said, “This time, you’re making it.”

There comes a moment in every man’s life when the woman he loves lays down a challenge.

It could be meeting her folks for the time.

Might be assembling some complicated piece of furniture.

Or unplugging a drain.

Or kayaking down the Intracoastal Waterway.

Or tending to the sale of a piece of property she wants to sell.

There’s almost always a new way to prove yourself worthy.

And so this time, I nodded and said, “Fine.”

The recipe I followed -- my wife’s via Betty Crocker with a few alterations of my own -- is astonishingly simple.

But in the back of my mind, as I boiled the potatoes, let them cool, removed the skins and cut them into cubes, was the possibility that I could actually fail.

That I’d concoct something inedible.

That I’d choke.

My wife didn’t help my state of mind when she look at the spuds I’d selected and said, “Those are way too big.”

Again, I trusted myself and said, “Just wait. You’ll see.”

And when I’d marinated them overnight in a blend of Italian dressing, secret spices and a prayer or two, she changed her tune.

“Well,” she said, as I began the layering and mixing process, “looks like you were right.”

“Again,” I almost replied, but settled for, “Thanks.”

Onions and celery, diced and stirred in followed and then three hard-boiled eggs, chopped two and sliced one ... a little more dressing, a toss or two with a spatula and a spoon and back into the refrigerator to allow all those tasty ingredients to get to know each other.

But when it’s all over and the music from the festival -- country, surf, shag and rock -- has faded away, the only thing that matters is the chance to spend a few hours with family, old friends and new friends.

I suppose that’s why things like my potato salad are called side dishes.

Because the main course is always something better.

Even if my wife said it was better than anything she’s ever concocted.

Even though folks seemed to enjoy it.

And even if I don’t know if I took it or brought it.
