A good friend texts to bail on dinner an hour before you're supposed to meet.
"Work ran late again, so sorry!"
You roll your eyes. Instead of letting it go, you catch yourself mentally listing the other three times they’ve rescheduled the last few months.
They are so bad at time management. You're building a case.
Later, when you're calmer, you remember: just yesterday, you forgot to call your mom back.
For the second day in a row.
But that was different. You've been slammed. She understands.
We do this constantly in close relationships. When we mess up, we've got reasons.
When they mess up, it's a pattern.
This is called self-serving bias - our tendency to attribute our successes and good behavior to who we are (our character, our effort), and our failures to circumstances beyond our control.
Meanwhile, we flip that script for other people. Their wins are luck or timing. Their mistakes reveal something about them.
It's not malicious. This bias serves as a core component of both healthy self-esteem and narcissistic traits, helping us maintain a positive view of ourselves.
When you forgot to call your mom, your brain immediately surfaced every legitimate reason why.
When your friend bailed on dinner, your brain surfaced every other time they've dropped the ball.
Here's what makes this especially tricky in relationships: the bias intensifies when we feel threatened.
When our competence or worth feels questioned, we double down on self-serving explanations.
That dinner situation from earlier? If you'd had a rough day and already felt like you were holding everything together, your brain was even more motivated to make this about them, not you.
The most functional relationships find ways to interrupt this pattern. Not eliminate it, we're human, but catch it before it calcifies into resentment.
First, track your own explanations. Mid-week is perfect for this. Next time you're annoyed at your partner or a close friend, notice the story you're telling yourself about why they did what they did. Then flip it: if you'd done the same thing, what would your excuse be? Usually, it's the same excuse they just gave you.
Second, get curious about "we" failures instead of "you" failures. When something goes wrong in a personal relationship, the question isn't "whose fault is this?" It's "what made this hard for both of us?" You didn't pick up groceries because you were fried. They didn't pick up groceries because they were fried. The system failed, not the person.
Third, practice giving your people the same grace you give yourself. Not as a moral obligation but as a cognitive correction.
You already know all the reasons you're doing your best under impossible conditions.
They're operating under the same deal.
If you catch yourself mid-spiral this week, building a case against someone you love, just pause. Ask: "Would I accept this explanation if it came from me?"
Usually, you already did.
Did this resonate with you? Forward it on to someone who could use it too. These insights are better when shared.
Cheers,
Alex
