Communicating with a difficult person can feel like navigating a minefield. Every message feels loaded. Every response could trigger an explosion. You spend hours crafting the "perfect" reply, only to get pulled into another exhausting exchange.
There's a better way. It's called BIFF.
What is BIFF?
BIFF stands for Brief, Informative, Friendly, Firm. It was developed by Bill Eddy at the High Conflict Institute specifically for communicating with high-conflict individuals.
The framework isn't about being passive or "winning." It's about giving the other person the information they need while protecting your peace and ending conversations efficiently.
Here's what each component means:
B = Brief
Keep your responses short. One paragraph maximum—often one sentence is better.
Why? Long explanations invite debate. Every sentence you write is another opportunity for them to find something to argue about. Short responses give them nothing to fight.
"I understand you're frustrated, and I want you to know that I've been trying really hard to accommodate your schedule, but sometimes things come up on my end too, and I think if we could just communicate better about this, we wouldn't have these problems..."
"I can do 5pm on Saturday."
I = Informative
Stick to facts. No emotions, no opinions, no defensiveness.
The moment you add "I feel like you always..." or "That's not fair because..." you've shifted from information to emotion—and emotion is where conflict lives.
Just the relevant facts. Nothing more.
"You always do this, but fine, I GUESS I can change my plans AGAIN even though you never appreciate it..."
"I can adjust the pickup time to 5pm on Saturday."
F = Friendly
This doesn't mean warm and fuzzy. It means professional neutrality.
Think about how you'd respond to a difficult coworker—polite, professional, not aggressive or passive-aggressive.
"Whatever you want."
"Of course! Anything you need! No problem at all!"
"Thanks for letting me know."
F = Firm
End the conversation. Don't leave openings for more back-and-forth.
Avoid questions like "Does that work for you?" or "What do you think?"—these invite continued debate.
"Does that work for you? Let me know what you think and we can discuss further."
"See you Saturday at 5pm."
BIFF in Common Scenarios
Scenario 1: The Accusation Avalanche
They send you a long message listing everything you've done wrong this month, your failures as a parent, and a request to change Saturday's pickup from 3pm to 5pm.
Your BIFF Response
"Thanks for sharing your concerns. 5pm works. See you Saturday."
That's it. You addressed the actionable item (the schedule change) and ignored everything else. No defense. No counter-attack. Just information.
Scenario 2: The Guilt Trip
"Everyone REALLY wants this to happen. You're being so selfish by not allowing this. I can't believe how unreasonable you're being."
Your BIFF Response
"I'm following the parenting plan. Let me know if you have questions about the schedule."
Scenario 3: Demand for Immediate Response
"I need an answer NOW. This can't wait. ANSWER ME."
Your BIFF Response
"I'll review this and respond by tomorrow."
Their urgency is not your emergency (unless it involves actual safety).
Scenario 4: Bringing Up the Past
"This is just like when you [thing from 3 years ago]. You've always been [negative trait]. Remember when you [another old grievance]..."
Your BIFF Response
"I'm focused on [current issue]. What do you need for Saturday's pickup?"
Why BIFF Works
High-conflict communication thrives on reaction. When you defend yourself, explain yourself, or match their energy, you're giving them exactly what they want—engagement.
BIFF gives them information instead of reaction. There's nothing to fight about in "5pm works."
Over time, many people find that BIFF responses actually reduce the overall conflict. When there's nothing to push against, some people stop pushing.
The Hardest Part
For most people, the hardest part of BIFF is letting go of the need to be understood.
We want to explain. We want them to see our side. We want them to acknowledge that we're trying, that we're reasonable, that we're a good parent.
But here's the truth most people learn the hard way: Defending yourself rarely changes their mind. It just extends the conflict.
Your BIFF response isn't about changing them. It's about protecting you.
When BIFF Isn't Enough
BIFF is a powerful tool, but it's not the solution for every situation:
- Safety concerns require different approaches—documentation, legal involvement, and professional support
- Genuine emergencies may require immediate engagement regardless of tone
- Court-ordered communication may have specific requirements
If direct communication isn't working even with BIFF, consider whether a more structured or limited communication approach might be a better fit for your situation.

Start small. The next time you receive a message that triggers you:
- Pause. Don't respond immediately.
- Identify the actionable item. What are they actually asking for?
- Draft a BIFF response. Brief, Informative, Friendly, Firm.
- Review it. Does it contain emotions? Defensiveness? Questions that invite more debate?
- Send it. Then move on with your day.
The first few times will feel uncomfortable. You'll want to add more. You'll want to defend yourself. Resist that urge.
With practice, BIFF becomes second nature. And when it does, you'll wonder how you ever communicated any other way.
