Try this
- List only the items that need joint coordination and assign each to one person.
- Keep personal packing separate. Before departure, verify the shared essentials are physically present rather than assuming a checked box reflects completion.
A worked example
“I’ll bring the charger and tickets; we’ll each pack our own clothes.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Check the shared items once before leaving rather than assuming duplicate preparation.
