Try this
- Identify what is actually finished and what remains, so the celebration does not conceal an unfinished handoff.
- Offer a small option such as tea outside or choosing dinner, with a clear choice to skip it.
A worked example
“The shelf is assembled and the tools are put away. Would you like to take a break together or have some time alone?”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Do not make celebration another required task. Resting separately can be an acceptable ending to shared work.
