Make room for the other version
Ask what the other person understood before assuming that you are arguing about the same facts. For a message about how to ask for a quieter place to work, use this factual base: use recent examples, observable impact, and the work requirement rather than labels about personality.
Correct the record precisely
Correct only what you can support, acknowledge any real impact, and propose a practical way to prevent repetition. Ask for a specific change, decision, or working agreement and choose a time to review it. Make the immediate next step clear enough that the recipient can answer without reconstructing the entire history.
Agree on a testable next step
Do not diagnose, gossip, embarrass a colleague, or turn one incident into a judgment about their character. Move harassment, discrimination, threats, health risk, and retaliation into the appropriate protected process. Do not recruit an audience, publish private evidence, or turn a misunderstanding into a campaign about character.
