Check who should receive the message
Confirm that you have the right person, the right role, and permission to disclose the information involved. For a message about how to support an autistic friend respectfully, use this factual base: use the person's description, note the access barrier or practical need, and avoid guessing about severity.
Separate information from interpretation
Label confirmed facts, open questions, and the specific decision that belongs to the recipient. Ask which accommodation or form of help is useful and follow through without making it a favor. Make the immediate next step clear enough that the recipient can answer without reconstructing the entire history.
Use formal help when stakes rise
Do not demand medical proof in a personal relationship, offer cures, or frame disability as inspiration. Use qualified clinical or emergency care for urgent health concerns and the proper rights process for denied accommodations. Medical, legal, financial, employment, and safety decisions may require a qualified professional rather than personal persuasion.
