Try this
- Choose an alternative that uses what you already have and does not require last-minute preparation.
- When weather changes the plan, ask whether the substitute or a free evening is preferable. Neither person owes participation in the replacement.
A worked example
“If the walk is rained out, let’s make soup or leave the evening free.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
A substitute is an option, not a requirement to preserve the routine at all costs.
