Try this
- Identify the actual planning action you know about, such as checking two schedules or finding an accessible route.
- Say what that action helped you do. Avoid broad claims about how the person always takes care of everything.
A worked example
“You checked the last train before we booked. That meant we could choose an ending time we can actually manage.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
If planning is repeatedly falling to one person, take ownership of a defined next task instead of relying on appreciation to make the arrangement sustainable.
