My grandmother leaned across the kitchen table, her weathered hands wrapped around a cup of tea. “You want to know the secret to staying married for fifty years?” she asked, even though I hadn’t asked. “Don’t say the thing you can’t take back.”
I was twenty-two at the time, fresh out of university with my psychology degree, convinced I knew everything there was to know about human behavior. Her advice seemed almost too simple. Too basic.
But here’s the thing: Fifteen years later, after writing about relationships, studying Buddhist philosophy, and navigating my own cross-cultural marriage, I’ve realized my grandmother accidentally stumbled upon what Dr. John Gottman calls the most important predictor of relationship success.
She was talking about contempt. And she’d never read a single research paper in her life.
The science behind grandma’s wisdom

When Gottman studied thousands of couples over decades, he discovered he could predict with 94% accuracy which marriages would last and which would fail.
The secret? Looking for what he calls the “Four Horsemen” of relationship apocalypse: Criticism, defensiveness, stonewalling, and contempt.
Guess which one is the worst? Contempt.
Those cutting remarks that come from a place of superiority, the eye rolls, the sarcasm dripping with disdain, and the words designed to wound rather than resolve; these are the things you can’t take back.
My grandmother didn’t know about Gottman’s research.
She didn’t have access to longitudinal studies or meta-analyses, but she understood something fundamental about human nature: Once certain words leave your mouth, they create wounds that even the most sincere apologies can’t fully heal.
Think about your own relationships: Can you remember something someone said to you in anger that still stings years later? Even if you’ve forgiven them, even if you’ve moved on, those words probably left a mark.
That’s the power of contempt; it erodes the foundation of respect that every healthy relationship needs to survive.
Why we say things we can’t take back
Here’s what I’ve learned through my own marriage and years of studying human behavior: We’re most likely to unleash contempt when we feel unheard, unappreciated, or overwhelmed.
It usually goes something like this: Small frustrations build up over time, your partner leaves dishes in the sink, they forget to call when they’re running late, and they dismiss your concerns about money or kids or whatever keeps you up at night.
Each incident feels minor on its own, but they accumulate like compound interest on emotional debt.
Then one day, something small happens. Maybe they make a joke at your expense or forget an anniversary.
Suddenly, all that built-up resentment explodes.
“You’re just like your mother.”
“I should have listened when everyone warned me about you.”
“Sometimes I wonder why I even married you.”
These are character assassinations as they communicate disgust with who your partner is as a person.
And once those words are out there? You can apologize, you can explain you didn’t mean it, but you can’t unhear what’s been said.
The antidote lives in everyday moments
So, how do you avoid saying the thing you can’t take back?
The answer isn’t just biting your tongue when you’re angry, though that helps. It’s about building what relationship researchers call “emotional bank accounts” during the calm moments.
Every positive interaction makes a deposit. Every expression of appreciation, every moment of genuine interest in your partner’s day, every small kindness adds to the balance. When you have a healthy emotional bank account, you’re less likely to go into contempt overdraft when conflict arises.
In my book, Hidden Secrets of Buddhism: How To Live With Maximum Impact and Minimum Ego, I write about the Buddhist concept of Right Speech. It’s about avoiding harmful words, and actively choosing words that heal, connect, and uplift.
This isn’t some mystical concept. It’s practical relationship maintenance.
When your partner irritates you, pause before responding.
Ask yourself: “Is what I’m about to say going to address the behavior, or attack the person?”
There’s a world of difference between “I feel frustrated when the dishes pile up” and “You’re such a slob.”
One opens a conversation, while the other closes a heart.
Learning from cultural differences
Moving to Vietnam and marrying into a Vietnamese family taught me something profound about communication styles and respect in relationships.
In many Asian cultures, there’s a concept of “face” that goes beyond simple embarrassment. It’s about maintaining dignity and respect, especially within intimate relationships.
Public criticism or contemptuous remarks damage something fundamental in the relationship fabric.
My wife taught me that in her culture, even private arguments rarely involve the kind of character attacks that are almost normalized in Western relationship conflicts.
There’s an understanding that some words create damage that can’t be undone.
This is about fighting fair, and remembering that the person you’re arguing with is someone you chose to build a life with, not your enemy.
The practice of pause
Want to know the most practical skill I’ve developed? The pause.
When I feel that surge of anger, that urge to say something cutting, I’ve trained myself to stop.
Sometimes I literally count to ten, take a walk, or I write out exactly what I want to say in a journal, then tear up the page.
This is wisdom because here’s what I know from both research and experience: Relationship quality is the single biggest predictor of life satisfaction.
The quality of our intimate relationships determines more about our happiness than almost anything else.
And most relationship problems? They stem from poor communication, saying things we can’t take back, and choosing contempt over compassion in moments of frustration.
What contempt really costs us
The real tragedy of contempt is what it does to us.
When we speak from contempt, we’re training our brains to see our partners through a lens of disgust and superiority.
We’re literally rewiring our neural pathways to notice what’s wrong rather than what’s right.
Over time, this becomes a filter we can’t turn off.
The person who once made us laugh becomes someone who annoys us; their quirks stop being endearing and start being evidence of their inadequacy.
This is how love dies: In the slow accumulation of contemptuous moments.
Final words
My grandmother passed away five years ago, just six months after my grandfather.
They were married for sixty-three years.
I never saw them have a perfect relationship—they argued about money, about family, and about the same things all couples argue about—but I also never heard either of them say something designed to wound the other’s core sense of self.
They understood something that all the relationship research in the world is just now catching up to: Respect is the oxygen of love.
Without it, even the strongest feelings suffocate.
So, the next time you feel that surge of contempt, that urge to say the thing that will really hit where it hurts, remember my grandmother’s wisdom and that some words create wounds that never fully heal.
Choose connection over contempt, repair over revenge, and to protect the foundation of respect that your relationship needs to thrive.
At the end of the day, being right isn’t worth being alone, and saying the thing you can’t take back might give you a moment of satisfaction, but it will cost you years of connection.
The choice is always yours.
