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 set guest limits with a roommate, use this factual base: record the property, room, payment, repair, behavior, and relevant lease or household agreement.
Offer support that can be accepted
Offer one specific form of practical or emotional support and make clear that no immediate reply is needed. Ask for one remedy with reasonable access and timing, then document what was agreed. 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 enter private space, withhold essential services, threaten eviction, or change locks without lawful authority. Use emergency, housing, tenant, health, or legal support for unsafe conditions, violence, or unlawful conduct. The recipient decides whether they want conversation, ordinary company, practical help, professional support, or quiet.
