Try this
- Label the note as unsent and retain its original context or approximate date.
- Store it separately from confirmed plans or shared records so it cannot be mistaken for something the other person received.
A worked example
“Unsent draft from before the June visit. My thoughts at the time; not a message or a joint agreement.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
If you revisit the topic later, write from current facts and preferences. Do not cite an unsent draft as evidence that the other person was told something.
