Everyday writing
Decline an invitation without a long excuse
A short, warm decline is harder to write than it sounds. It should say no clearly, keep the relationship intact, and avoid an excuse that could come back to you later.
What to check in the draft
Check that the draft gives only the reason you supplied. If you wanted to keep the reason private, remove hints or invented conflicts. Name the actual invitation so the message feels addressed to this person. Include a rain check only if you intend to follow through.
After you review the draft
If the relationship matters to you, ask yourself whether a handwritten note would land better than a text. For a close friend, add one sentence the assistant can't supply: something specific about the invitation that shows you read it.
