How to Say the Hard Thing Without Starting a War

I came out of childhood hating and fearing conflict. The violence of my parents’ arguments taught me that the safest option was to shut up, move away, and pretend nothing had touched me. So I learned to avoid conflict. More precisely: I learned to deny my emotions, to swallow them, and to tell myself that I was "above all that". That it didn’t matter. That I was fine. Except, of course, I wasn’t. Life has since shown me, repeatedly, that this way of reacting is destructive. Avoiding conflict may look peaceful from the outside, but it often means denying yourself. It prevents the relationship from becoming more genuine. Sometimes it leads to a premature end. Sometimes, worse, it leads to a long fossilisation: the relationship continues, but in a frustrating, fake, unfulfilling version of itself. On the other hand, conflict is not necessarily bad. Between avoidance strategies and warlike confrontation, there is a third way. A way that does not require you to disappear, and does not require you to attack. Let me call it (drumroll)… The path of constructive assertiveness. 💡 Constructive assertiveness is the art of speaking your mind without trying to hurt, dominate, or humiliate the other person. It is not about “winning” the conversation. It is not about proving that you are right and the other person is wrong. It is about bringing something real into the relationship, instead of letting it rot in silence. When it works, it strengthens trust. And when it doesn’t work, at least you know where you stand. In this short article, I want to share a few principles that help me speak more truthfully in daily life, without alienating the whole planet. The third way When something hurts us, annoys us, disappoints us, or makes us angry, we often see only two options. The first one is avoidance. > “It’s fine.” ... Although it's not. The second one is attack. > “You’re selfish.” “You’re mean.” “You never listen.” “You always do this.” This may feel satisfying for about three seconds, but it never fails to put the other person on the defensive. And once people are defending themselves, they are not listening anymore. Constructive assertiveness is the third way. It sounds more like this: > “When this happened, I felt this way, and next time I would need this.” That’s it. Simple, not easy. How does it work ? Start with facts Facts. Not your interpretation. Not your diagnosis of the other person’s personality. Not the courtroom version where you are the prosecutor and they are the accused. Just the facts. For example: > “Yesterday, during the meeting, I was interrupted several times while trying to explain my idea.” Instead of: > “You don’t respect me.” Maybe the person does not respect you. Maybe they do. Maybe they were stressed, clumsy, excited, distracted, or just being an asshole in that moment. You don’t need to solve their soul immediately. Start with what happened. Facts create a shared ground. They give the conversation a chance. Speak as “I” A coach once talked to me about the police siren effect of the word “you”. You… you… you… It sounds like an alarm. It immediately makes the other person feel accused. > “You are mean.” “You humiliated me.” “You don’t care.” Sometimes it may even be true. But it is rarely the best way to open a constructive conversation. It is much less aggressive to speak from “I” and say what happened inside you, the impact the facts had on you. > “I felt humiliated by your reaction.” This does not mean that your feelings are the only thing that matters. It simply means that you are taking responsibility for your side of the experience. You are not pretending to be inside the other person’s head. You are sharing something that cannot be contested: your personal experience. You're owning your vulnerability, which is strength, not weakness. > Vulnerability sounds like truth and feels like courage. Truth and courage aren't always comfortable, but they're never weakness. – Brené Brown Point to the behaviour, not the person. There is a huge difference between: > “You are selfish.” And: > “When you changed the plan without telling me, I felt left out of a decision that also affected me.” The first sentence attacks the person’s identity. The second one points to a specific behaviour and its impact. We all make mistakes. We are all clumsy. We all sometimes behave in ways that hurt others without intending to. If you attack the person, they will probably defend their identity. If you name the behaviour, there is at least a chance they can look at it. Choose your words carefully Some words have the magical ability to ruin a conversation before it even starts. “Always.” “Never.” “But.” These words often put people on the defensive because they sound final, exaggerated, or oppositional. > “You never listen.” Really? Never? Now the other person only needs to find one example where they listened, and the conversation becomes a stupid debate about the word “never”. Prefer words that leave some room. > “I often feel like I’m not being heard.” “For the moment, this does not work for me.” “I understand your point, and I also see it differently.” Try to use “and” instead of “but” when possible. > “I hear what you’re saying, but…” Usually means: > “I heard the noise of your words, and now I will explain why you’re wrong.” Whereas: > “I hear what you’re saying, and I also need to say how I experienced it.” This keeps both realities in the room. It may sound like a detail. It is not: words create posture. Use the simple formula The most useful structure I know is: Fact → feeling → request. Or, when it is too early to propose a solution: Fact → feeling → open question. Example: > “When the deadline changed yesterday without warning, I felt stressed because I had already organized my week around the previous plan. Next time, could you tell me as soon as you know?” Another example: > “When you made that joke in front of the team, I felt embarrassed. I know you may not have meant it that way, and I’d prefer that kind of joke not be made publicly again.” Another one: > “When I sent you the message and didn’t get an answer for three days, I started wondering if something was wrong. Could you let me know next time if you need more time to reply?” This is not weakness. It is precision. You are not putting the other person on trial. You are showing them the impact of a specific behaviour, and giving them a possible way forward. I can only recommend reading Lara Hogan's excellent article on the “feedback equation” that goes deeper into this idea. Aim for the future The past is useful as evidence, but the future is where the relationship can still improve. So instead of trying to rewrite the past, which is impossible, try to make the next occurrence better. Instead of: > “You should have told me sooner.” Try: > “Next time, could you tell me as soon as possible?” Instead of: > “You shouldn’t have said that.” Try: > “Next time, could you tell me this privately rather than in front of the group?” Instead of: > “You made the whole thing more difficult.” Try: > “Next time, I’d like us to agree on the process before making the decision.” It does not mean the past does not matter. It means the conversation is more useful when it creates a possible future. Choose the time and the place If possible, avoid reacting on the spot, at the height of a strong emotion. This is difficult, because strong emotions often come with a very convincing sense of urgency. > “I need to say this now.” What you need first is to calm down enough to say it properly. There is a difference between being honest and throwing your emotional furniture at someone. The right place matters too: if you need to reframe someone, avoid public shaming. Isolate yourself with the person. Give the conversation some privacy and dignity. At work, if the mutual trust is low, you can also ask an HR person, a manager, or a neutral third party to be present. Not to create a tribunal, but to facilitate the discussion and give a more official frame to it. A good message delivered in the wrong setting can still do damage. Of course... It takes two to tango These are tricks. They have helped me many times, with adults, colleagues, friends, and especially with my teenage children, when I have to reframe them without turning the whole thing into World War III. But constructive assertiveness is not a magic spell. You can choose your words carefully. You can speak from “I”. You can focus on the behaviour. You can aim for the future. You can be honest without being aggressive. And still, the person in front of you may choose the fight. That part is not under your control. Some people are not interested in dialogue. Some people only want to win. Some people hear any feedback as an attack. Some people are committed to living a shitty life, and it is their sacred right to do so. At least you know where you stand. You did your best to be constructive. You behaved like an assertive yet non-aggressive human being. That is something to be proud of. In truth, it is total class. And somewhere along the way, you made the world a little better by bringing your authenticity to it instead of your silence or your violence. Assertiveness is not only for conflict One last thing. These principles also work for positive feedback. Expressing thanks in an assertive way makes it so much richer. Instead of: > “Thanks, that was great.” You can say: > “Thanks. When you took the time to explain the situation clearly, it helped me feel reassured and more confident about the next steps.” Instead of: > “Good job.” Explain why it was good to you: > “The way you handled that conversation was calm and precise. I think it helped everyone stay focused.” Constructive assertiveness is not only about saying hard things. It is about saying true things, and relationships need that. 💡 What about you? Have you discovered any tips or tricks that help you navigate life’s conflicts in a constructive way?
