Try this
- Name an effort you know happened, such as making a booking or preparing food.
- Acknowledge the actual disappointment too. Do not insist that gratitude should replace an honest account of the result.
A worked example
“The event being canceled was disappointing. I still noticed the work you put into arranging the evening.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
If a practical problem needs fixing, discuss it separately. Appreciation does not require declaring the failed plan successful or overlooking a repeated logistical issue.
