Recognize what makes this moment difficult
Acknowledge the event directly without turning it into a lesson, comparison, prediction, or silver lining. For a message about how to support someone after a flood, use this factual base: confirm what they have shared, their current location or immediate need, and avoid repeating unverified information.
Offer support that can be accepted
Offer one specific form of practical or emotional support and make clear that no immediate reply is needed. Offer one concrete resource, task, safe place, transport option, or flexible check-in. Make the immediate next step clear enough that the recipient can answer without reconstructing the entire history.
Follow their pace rather than yours
Do not photograph, publish, fundraise in their name, or arrive at a crisis site without permission. Follow local emergency, evacuation, shelter, trauma, and safeguarding guidance before relying on a personal message. The recipient decides whether they want conversation, ordinary company, practical help, professional support, or quiet.
